FYI, Fedora ships (only) r600g, not r600 Classic, so the debugging output even in GLX mode will look very similar, if not identical, to your OpenGL ES one. Sometimes helping KWin on what the hardware really supports can … the debug output I showed is wih r600g. Content is available under, Tutorial 2 - composite transition and Blue Screen, https://userbase.kde.org/index.php?title=Kdenlive/Manual/Transitions/Composite&oldid=455450. Could you at least tell us a bit more about your configuration and experiences with GLES, nouveau and 3D performance? There are two many hardware/driver/Xorg/kernel combinations to say anything about it. >but telling the nvidia driver to clean it’s cache helps. KDE SC 4.6 was released on 26 January 2011 and has better OpenGL compositing along with the usual myriad of fixes and features. But as we do not make use of anything provided by OpenGL 3, there is no need for this. ... Thats explicitly stated in KDE, with a disable in fullscreen option. This mode can be entered at all time by the Shortcut Alt+Shift+F12 and in the General Desktop Effects settings through option “Enable desktop effects at startup”. On the other hand on DEs like LXDE, compositing is not available by default. Under Workspace Appearance and Behavior, click “Desktop Effects”. I was a little bit depressed after see my composite performance descend because of the OpenGL 2.0 backend, and reading that I could enable the old 1.X based made my day :)! KDE is happy to announce the immediate availability of Plasma Desktop and Plasma Netbook 4.6. Some of those effects you enjoy from KWin are available in other compositing engines. This means especially for distributions: don’t use the build flag for the default package, but provide an additional one. I am back to the blob on my nvidia system. Amazing stuff has been landing left and right every day this week! KDE 4.0.5 Changelog : KDE.org Changes in KDE 4.0.5 kdelibs[ all SVN changes ] klauncher Bugfixes: Remove reading of X … Is it nvidias fault? Docky. KDE compositing in openSUSE11.1 Submitted by Lubos Lunak As you might have noticed, KDE 4.1.3 has been released , codename "Change" (in line with other C- codenames recently, as a kind of a joke on all those people who fail to see that still writing comments with overuse of K after 10 years of KDE's existence can only be a sign of brain damage). Will it be fixed with the new modes in KDE4.7? Fortunately, there is a way to give lightweight desktop environments true window compositing. Top. Not really a backend, but also a mode which has to be mentioned. The programmable pipeline is a way nicer API to write GL code and especially the ES code can benefit users as it throws out all the legacy code and state tracking, which is rather complex in OpenGL and should ensure better drivers. It uses only the so-called programmable pipeline or also known as the “core” profile. KDE's software runs on GNU/Linux, BSD and other operating systems, including Windows. KDE. When I was running blob I noticed that sometimes I had to switch off the computer and switch it on again to gain back performance so this might be related. And I think my experience is not of interest to anyone as it is not representative. The legacy backend is used automatically for all drivers not supporting at least OpenGL 2.0 and the fglrx driver. Disable compositing. Be aware that EGL is not supported by all drivers. The code uses only fixed functionality. As far as I know from your previous posts you are testing the OpenGL 2 ES mode on a nvidia based machine. OpenGL 3.0 provides support for frame buffer objects, hardware instancing, vertex array objects, and sRGB framebuffers." no as we don’t know that. OpenGL shading language version string: 4.10 NVIDIA via Cg compiler It’s responsible for any fancy effects like drop-shadows, as well drawing windows while dragging, resizing and minimizing or maximizing them. Without that, my system becomes unusable within half a day. See this tutorial that describes how to use: Tutorial showing how to use the "Blue screen" function, composite transition and Keyframes to animate one image moving over another in the Kdenlive video editor. Especially the “minimize animation” is noticeably sluggish, when I unminimize a window. There should be three messages for valid - then OpenGL 2 is used or at least one message on failure, then OpenGL 1 is used. KWin does nowhere log which backend is really used, but there are some messages printed to stdout which can help recognizing the version. Not really a backend, but also a mode which has to be mentioned. KDE … Some highlights are touch support in Dolphin, user-configurable per-view sort ordering in Elisa, optional Systemd startup,… The Composite transition combines the video data from two video tracks into one. eg. KDE SC 4.6. I deactivated "Use of Hardware Acceleration" but left "Compositing in KDE settings" activated (OpenGL 3.1). I have massive slow downs in KDE4 (a lot of different nvidia binary drivers tested – and always using the latest KDE). radeon | 60.8k Warning: video below may be inappropriate for some users. intel (mesa 7.11 )| Thank you very much for the clarification. The clip with alpha information is located on the bottom track: the selected color acquires transparency. According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. 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. if OpenGL 2 is not available OpenGL 1 is used. nouveau | I noticed the driver always reported the RAM with 512MB instead of the 256MB for my gfx. I switched my XFCE machines over to use Compton for window compositing today - and it’s a noticeable improvement.. A compositor glues your stacks of windows together to form the final image that you see on screen. This transition is used in combination with Alpha Channel information supplied by one of the Alpha Manipulation Effects or by the use of a Wipe File. Thanks for the write-up, and I agree that it is rather nice to see how far the XRender backend has come. GLSL shaders: yes Martin, is it possible to run fglrx with OpenGL 2 backend? One of the first systems with a compositing windowing system was the Commodore Amiga, released in 1985. Open “System Settings” from the K-menu or press Alt+F2 and type “System Settings”. SPOILER ALERT: Scroll down and watch the video tutorial at the end of this article. Applications could first request a region of memory outside the current display region for use as bitmap. 50.4k Simply alt-tabbing out does not re-enable compositing like on GNOME 3. It can be selected in the advanced Desktop Effect settings in the dropdown “Compositing type”. X server version: 1.9.3 In opposite to the other two OpenGL backends this one is not a runtime option, but a compile time option. According the FAQ, KDE Neon isn’t quite a Linux distribution. I can't find the option in XFCE. 1 Reply Last reply . Aspirational goal - a compositing experiment made using detonation films free sample effects. Anyway, such a test probably doesn't really say much. KDE is an international and diverse technology team creating user-friendly free and open source software for desktop and portable computing. Even disabling the KDE desktop effects doesn’t help, but telling the nvidia driver to clean it’s cache helps. Composite effects are stunning on KDE. However, Martin Graesslin has revealed some details about what they are planning for KDE 4.7. Software Rasterizer). You need to change it to 99% to make the effect kick in. Performance on the backend depends on the driver, but can be rather fair (I once did not notice that the XRender backend was used in a virtual machine). I have been also feeling your pain too :-). It would appear that you need to stop and restart Kdenlive in order for it to pick up new matte/wipe files saved in the above directory. stewbrew on Mar 25, 2018. Lately I noticed that there is some misunderstanding on what are the differences between the modes, why we wrote new code and what is the best mode for whom (at least one distribution did it wrong in their first packaging approach). So the old code would simply not compile against the libraries and that’s why it is a compile time option. Many apps require compositing for proper working. The clip with alpha information is located on the bottom track: everything in the image becomes transparent, except for the selected color. The performance depends on settings which are different between KWin and Compiz and in 4.7 we changed the default, so we behave like Compiz. All my Arch's prior Plasma versions also correctly supported Vivaldi manual resizing [& again always using compositing]. always gives me responsive edge & corner handles. Well i don know, i posted it in a comment beacuse it has kde+kwin in the comparation, the results seem good to KDE. my notebook uses a Nvidia Quadro NVS135M gpu and for quite some time (years?) This is our default compositing backend. Last but not least to give our users the best possible performance and user experience. No Compositing. intel (mesa 7.10 )| This transition is used in combination with Alpha Channel information supplied by one of the Alpha Manipulation Effects or by the use of a Wipe File. This can be quite tricky, because KWin automatically falls back to a different backend if one fails. KWin always prints out the used OpenGL version information. Until you define some alpha channel data using an Alpha Manipulation Effect or a Wipe File, changes in the Composite transition settings will have no visible effect. https://bugs.kde.org/show_bug.cgi?id=273697 When I minimize all the other apps, the sliding down animation is a bit smoother. Kubuntu 14.04, KDE 4, HD5770, no flickering. This is why I leave it disabled and just switch off compositing if I actually need the best performance (alt+shift+f12) and reenable it when I'm finished playing (alt+shift+f12). It’s primary target are mobile devices (Plasma Active), but also on the desktop it is very important as it is the requirement for supporting Wayland. Disabling compositig in kwin is known to fix glitches such as parts of windows being displayed in random places, seemingly corrupted framebuffer, and similar.
