Compositor > OpenGL => XRender. Многие эффекты не доступны с XRender. It is nothing quantitative, but when scrolling long pages in Firefox or looking at how desktop behaves when 'fade away' effect is enabled, I feel that OpenGL performance isn't as good as XRender. Builds support for KDE's Activity concept. Although it's technically not needed to port everything, we want to port all of KWin over to XCB as XCB has many advantages over XLib, most important that it is an async API. Default: ON. Tearing is caused by Xrender (which is used to composition in Xfwm4), which can't sync (I can't belive that, but it's true). This document is used to keep track of various parts which need to be ported and to organize an collaborative approach towards the porting.

Switching the compositor from OpenGL to Xrender stops this from happening. I'm using XFCE 4.10 on Arch Linux (3.14.4) with Nvidia drivers (337.19). XRender mode in general has less features, at the moment it is also considered unstable since it has not received as much testing as OpenGL mode. Great hint regarding tearing - for me it already completely went away by switching from XRender to OpenGL 3.1, no other settings were needed :-) – Torsten Römer Jan 22 '17 at 18:31 Content is available under, X Rendering Extension Protocol Specification, https://community.kde.org/index.php?title=KWin/Xcb&oldid=28609, Note: in Qt 5 a QPixmap does no longer reference an X11 Pixmap.

It is nothing quantitative, but when scrolling long pages in Firefox or looking at how desktop behaves when 'fade away' effect is enabled, I feel that OpenGL performance isn't as good as XRender. Builds support for KDE's Activity concept. Although it's technically not needed to port everything, we want to port all of KWin over to XCB as XCB has many advantages over XLib, most important that it is an async API. Default: ON. Tearing is caused by Xrender (which is used to composition in Xfwm4), which can't sync (I can't belive that, but it's true). This document is used to keep track of various parts which need to be ported and to organize an collaborative approach towards the porting.

Switching the compositor from OpenGL to Xrender stops this from happening. I'm using XFCE 4.10 on Arch Linux (3.14.4) with Nvidia drivers (337.19). XRender mode in general has less features, at the moment it is also considered unstable since it has not received as much testing as OpenGL mode. Great hint regarding tearing - for me it already completely went away by switching from XRender to OpenGL 3.1, no other settings were needed :-) – Torsten Römer Jan 22 '17 at 18:31 Content is available under, X Rendering Extension Protocol Specification, https://community.kde.org/index.php?title=KWin/Xcb&oldid=28609, Note: in Qt 5 a QPixmap does no longer reference an X11 Pixmap.

In ~/home//.kde/share/config/kwinrc the use of OpenGl can be forced by adding the following lines to the compositing-section: The invert Effect is a real useful effect because it helps one to read text for longer duration without straining the eyes. One of KWin's compositing backends is based on XRender. Its design was influenced by rio, the windowing system for Plan 9. You'll miss out a few OpenGL desktop window transition effects, but the MASSIVE boost in performance should be well worth it. I hope I'm reporting this correctly and to the right place. My primary use of compton is to get rid of tearing (I use GTX 560 Ti & Dell U2711). KDE is an open community of friendly people who want to create a world in which everyone has control over their digital life and enjoys freedom and privacy. It is designed to target the 3D graphics capabilities of newer video cards. KWIN_PLASMA_ACTIVE.

xrender vs opengl kde

XRender доступен даже если драйвер OpenGL не установлен (например, виртуальные машины) и использует в основном центральный процессор для отрисовки. As an example for implementing a new Compositor this commit can be used. It appears that WSL doesn't currently have much if any support for hardware acceleration with OpenGL, so you should set your KDE Plasma window compositor to run on the Xrender backend rather than OpenGL 2 or 3.1. The Compositing type allows choice of the compositing backend, either XRender or OpenGL. [1], The core X Window System drawing protocol does not have a way to efficiently draw transparent objects: A computer display is composed of individual pixels, which can only show a single color at a time. It is because KDE (plasma) falls back to Xrender if . Compton does its job perfectly when running compton --config /dev/null --backend xrender --vsync opengl. The porting has a low priority for the core KWin team as the default compositing backend is OpenGL and it is possible to disable building KWin with XRender support. So Qt/3D is an extension to the normal Qt OpenGL module. My primary use of compton is to get rid of tearing (I use GTX 560 Ti & Dell U2711). KDE is happy to announce the immediate availability of Plasma Desktop and Plasma Netbook 4.6. The Plasma Workspaces have seen both polish in existing functionality as well as the introduction of significant new innovations extending Plasma's capabilities further towards a more semantic, task-driven workflow. Many effects are not available with XRender. The specific compositors are implemented as a sub class of the abstract base class KWin::Scene and a few more classes. As an example for implementing a new Compositor this commit can be used. XRender доступен даже если драйвер OpenGL не установлен (например, виртуальные машины) и использует в основном центральный процессор для отрисовки. From my experience, graphics cards with good 3D hardware and drivers should always use OpenGL. One of KWin's compositing backends is based on XRender. Qt, and therefore KDE, deals with 3 predominant ways of rendering graphics. I had a really strange problem on my laptop where KDE / the whole system got very slow after browsing / watching youtube videos. The bug is there for years - tearning video, tearning windows, and so on. By default OpenGL is used which is hardware accelerated. Default: ON (OFF for GLES only builds) Builds OpenGL 1 based compositing support Since 4.10, Removed in 5.0. Flickering stops when I change Compositor Rendering Back-end To OpenGL 3 and then change again to OpenGL 2. Those three ways are: On the CPU with no help from the GPU using the raster engine; Using X11/Xrender with the X11 engine; Using OpenGL with the OpenGL engine KDE 4.7.1 Changelog : KDE.org Changes in KDE 4.7.1 kdelibs[ all SVN changes ] khtml Bugfixes: Fix konqueror freeze when rendering some tables with zero colspan/rowspan. The Plasma Workspaces have seen both polish in existing functionality as well as the introduction of significant new innovations extending Plasma's capabilities further towards a more semantic, task-driven workflow. Default: ON. XRender; OpenGL 1; OpenGL (ES) 2; with OpenGL 1 and 2 sharing a lot of code. I could try OpenGL compositing but I feel it isn't quite there. It was written by Keith Packard in 2000 and was first released with XFree86 version 4.0.1. I can even switch to openGl and everything is fine. When using Anydesk to connect to my home computer running Arch Linux I experience severe graphical glitches (flickering) when I remote in. Over the last few months the KWin development team worked on bringing the Window Manager for KDE's Plasma workspaces to mobile devices. It provides several rendering operations and also does alpha blending. I can only enable them by setting composition type to XRender and I can not set them to openGl. Hi, by playing around with KDE 4.1 I have switched from OpenGL to XRender by accident. The specific compositors are implemented as a sub class of the abstract base class KWin::Scene and a few more classes. XRender mode. Nevertheless it should be ported as users of the XRender compositor would benefit from a port to xcb. I have diabled nearly everything, but still not possible to switch back to OpenGL. The X Rendering Extension (Render or XRender) is an extension to the X11 core protocol to implement image compositing in the X server, to allow an efficient display of transparent images. Nevertheless it should be ported as users of the XRender compositor would benefit from a port to xcb. With the migration of KWin's codebase to git, the code was imported into the master development tree to be part If you are interested in working on one of the parts just add yourself to the specific item. KDE 4.7.1 Changelog : KDE.org Changes in KDE 4.7.1 kdelibs[ all SVN changes ] khtml Bugfixes: Fix konqueror freeze when rendering some tables with zero colspan/rowspan. KDE is happy to announce the immediate availability of Plasma Desktop and Plasma Netbook 4.6. Nevertheless it should be ported as users of the XRender compositor would benefit from a port to xcb. The porting has a low priority for the core KWin team as the default compositing backend is OpenGL and it is possible to disable building KWin with XRender support. Default: Enabled for KDE_PLATFORM_PROFILE not Desktop This disables pretty much every desktop effect, while keeping the compositor semi-enabled. January, 26th 2011. System Properties for All Platforms opengl. KWIN_PLASMA_ACTIVE. One of KWin's compositing backends is based on XRender. Over the last few months the KWin development team worked on bringing the Window Manager for KDE's Plasma workspaces to mobile devices. With the migration of KWin's codebase to git, the code was imported into the master development tree to be part The exact steps are described in this document. The X Rendering Extension (Render or XRender) is an extension to the X11 core protocol to implement image compositing in the X server, to allow an efficient display of transparent images. The exact steps are described in this document. The Activities system has been redesigned making it easier to take advantage of them.

KDE is an open community of friendly people who want to create a world in which everyone has control over their digital life and enjoys freedom and privacy. You'll miss out a few OpenGL desktop window transition effects, but the MASSIVE boost in performance should be well worth it. However, the standard X protocol only allows drawing with solid color, so the only way to achieve transparency is to fetch the background color from the screen, mix it with the object color, then write it back, which is fairly inefficient.[2]. There are two choices here: OpenGL (3D) and XRender (2D). OpenGl fails because of an error or ; it does not enable OpenGl because it detects that the graphics card or the graphics driver is not "safe" to run with OpenGl. Re: KWin compositing only in XRender mode / unable to use OpenGL Sun Nov 29, 2009 8:26 pm Since you are using KDE 4.3, it is likely you have found a bug in the operation of KWin's desktop effects with multiple screens ( probably due to the lack of using Kephal ) The porting has a low priority for the core KWin team as the default compositing backend is OpenGL and it is possible to disable building KWin with XRender support. OS: KUbuntu 15.04 Graphics: Intel HD 4000 Geometric figures are rendered by client-side tessellation into either triangles or trapezoids. Writing a single OpenGL application that runs on all platforms is quite difficult, even for simple objects. Compton does its job perfectly when running compton --config /dev/null --backend xrender --vsync opengl. I'm using the proprietary nvidia driver, if that makes a difference. Builds XRender based compositing support KWIN_BUILD_OPENGL_1_COMPOSITING. Contrary what manual says, for me GLX backend is significantly slower than xrender. Nvidia and AMD cards usually fall into this category, although the AMD/ATI drivers may vary … Builds support for KDE's Activity concept. Intended use: To enable the OpenGL-based pipeline, which provides hardware acceleration. Purchase books, mugs, apparel, and more to support KDE. Solution is to fix Xrender, or teach Xfwm4 to use OpenGL, or use Compiz. Contrary what manual says, for me GLX backend is significantly slower than xrender. It's defaulted to OpenGL 2.0 on my machine, but is there any benefit in using OpenGL 3.1? It would be nice to have Invert effect for XRender without opengl (where opengl is not working (most GPU)) in KDE. Thus transparency can only be achieved by mixing the colors of the transparent object to be drawn with the background color (alpha compositing). Contrary to what is stated here, I can report much better performance using OpenGL instead of Xrender with Intel HD Graphics on Kubuntu 12.04. When I try to switch back to OpenGL it says alwaysthat it is not possible, because of the Desptop effects. It appears that WSL doesn't currently have much if any support for hardware acceleration with OpenGL, so you should set your KDE Plasma window compositor to run on the Xrender backend rather than OpenGL 2 or 3.1. XRender; OpenGL 1; OpenGL (ES) 2; with OpenGL 1 and 2 sharing a lot of code. KWIN_BUILD_ACTIVITIES. The login hangs were gone after updating to 16.10, so unfortunately I cannot confirm but I am sure it does solve the issue. Does anybody has a idea where to look (e.g. There is also a render-util library available for which unfortunately the API documentation is lacking. The X Rendering Extension (Render or XRender) is an extension to the X11 core protocol to implement image compositing in the X server, to allow an efficient display of transparent images. This has required porting the compositing code to OpenGL ES 2.0, the open graphics API for programmable embedded graphics hardware. Default: Enabled for KDE_PLATFORM_PROFILE not Desktop In order to go to Qt 5 KWin needs to be ported from XLib to XCB. As of 2011[update] it serves primarily to implement antialiased fonts, but for example KWin, KDE’s window manager uses it to draw drop shadows and translucency in case OpenGL is not available. config files) so I can revert the changes by hand? When I boot with KDE desktop effects Compositing type set to XRender all works. XRender is available even if no OpenGL driver is installed (e.g. This has required porting the compositing code to OpenGL ES 2.0, the open graphics API for programmable embedded graphics hardware. Since many operations require transparency (for example spatial anti-aliasing, especially during font rasterization, and transparency effects in window managers, such as transparent windows or menus), this limitation caused problems, and Xrender was implemented to address it. Before starting to work on it, it might be a good idea to have a look at the X Rendering Extension Protocol Specification as the API is derived from the protocol description. XRender. I am facing flickering in KDE Plasma 5.4. Text is drawn by loading the glyphs into the server and rendering as a group. Default: ON (OFF for GLES only builds) Builds OpenGL 1 based compositing support Since 4.10, Removed in 5.0. The header file is xcb/xcb_renderutil.h. I'm using XFCE 4.10 on Arch Linux (3.14.4) with Nvidia drivers (337.19). I notice there is an option under Settings/Display and Monitor/Compositor to change the rendering backend for the desktop effects. Contents 1 History It is possible to use XRender for compositing instead of the default OpenGL. System Settings > Compositor > OpenGL => XRender. Многие эффекты не доступны с XRender. It is nothing quantitative, but when scrolling long pages in Firefox or looking at how desktop behaves when 'fade away' effect is enabled, I feel that OpenGL performance isn't as good as XRender. Builds support for KDE's Activity concept. Although it's technically not needed to port everything, we want to port all of KWin over to XCB as XCB has many advantages over XLib, most important that it is an async API. Default: ON. Tearing is caused by Xrender (which is used to composition in Xfwm4), which can't sync (I can't belive that, but it's true). This document is used to keep track of various parts which need to be ported and to organize an collaborative approach towards the porting. Builds XRender based compositing support KWIN_BUILD_OPENGL_1_COMPOSITING.

Switching the compositor from OpenGL to Xrender stops this from happening. I'm using XFCE 4.10 on Arch Linux (3.14.4) with Nvidia drivers (337.19). XRender mode in general has less features, at the moment it is also considered unstable since it has not received as much testing as OpenGL mode. Great hint regarding tearing - for me it already completely went away by switching from XRender to OpenGL 3.1, no other settings were needed :-) – Torsten Römer Jan 22 '17 at 18:31 Content is available under, X Rendering Extension Protocol Specification, https://community.kde.org/index.php?title=KWin/Xcb&oldid=28609, Note: in Qt 5 a QPixmap does no longer reference an X11 Pixmap.

In ~/home//.kde/share/config/kwinrc the use of OpenGl can be forced by adding the following lines to the compositing-section: The invert Effect is a real useful effect because it helps one to read text for longer duration without straining the eyes. One of KWin's compositing backends is based on XRender. Its design was influenced by rio, the windowing system for Plan 9. You'll miss out a few OpenGL desktop window transition effects, but the MASSIVE boost in performance should be well worth it. I hope I'm reporting this correctly and to the right place. My primary use of compton is to get rid of tearing (I use GTX 560 Ti & Dell U2711). KDE is an open community of friendly people who want to create a world in which everyone has control over their digital life and enjoys freedom and privacy. It is designed to target the 3D graphics capabilities of newer video cards. KWIN_PLASMA_ACTIVE. Desktop OpenGL, OpenGL/ES 1.1, and OpenGL/ES 2.0 use different function names, and shaders versus fixed function pipelines. Thank you so much for pointing this out! virtual machines) and uses mostly the CPU for rendering. Contents 1 History Some features may be incomplete and it is recommended to use the OpenGL mode if possible.
