--- Comment #7 from Martin Flöser <[email protected]> --- I just checked the code to see what the cases are for EGL to be picked: 1) if the env variable is set 2) if on Wayland 3) if compiled without GLX support 4) if Qt is compiled with OpenGL ES support 5) if KWIN_COMPOSE env variable is set to O2ES 6) if X display does not support GLX As you explicitly set the env variable to be glx we can exclude 1. Your support information excludes 2, 3 and 5. So we have either Qt being compiled with OpenGL ES (but then it should be OpenGL ES IIRC) or X not supporting GLX. Given that you write that you have the nvidia driver installed, but KWin uses Intel driver I bet on number 6 being the actual issue. You can easily verify by e.g. running glxinfo or xdpyinfo. -- You are receiving this mail because: You are watching all bug changes.
