Didn´t mention it, but it is clear from the context: When using GLX bindings no flickering at this point. There is some occasional flickering in game since update to latest mesa, but its not as persistent and large as the one I have with EGL bindings. Compositing is set to OpenGL 3.1 here. Does this also happen on a singlescreen setup (external screen OR internal screen)? Does it also happen with a) es2gears_x11 b) glxgears I don't know "planeshift", but from your description, it sounds like only a fraction of the planameshift scene "flickers" while the rest of the scene/screen/display is ok? Eg. what happens in a windowed mode (all screen flickers or just the game or just the rotating character) Please attach the outputs of qdbus org.kde.KWin /KWin supportInformation glxinfo -l # sic! I want to see the HW limitations of the IGP ;-) Okay, during playing PS just the things that are easy to do in between. Flickering is only on one half of the PS fullscreen window, where the displayed char rotates, but that may be related to were the gfx is updated. I think this may be the case, cause the flickering areas changed after I logged in and the in game scene renderings with the in game gui controls begins. With GLX binding I can provoke some flickering with window compositing effect (i.e. where it displays all windows on current screen), but its only temporary. The flickering with EGL bindings are permanent. I will attach the outputs you mentioned. Created attachment 93995 [details]

errrr... on the broken setup, please ;-)
In addition, you may want to try
export KWIN_USE_BUFFER_AGE=0
kwin_x11 --replace &
The option to select EGL got removed as it was in general too broken on most systems. It's still possible to use EGL by setting the env variable or manually editing the config file, but one is on own risk then. |
