--- Comment #15 from Tavian Barnes <taviana...@gmail.com> --- I haven't reproduced it yet with debug symbols, but I did some additional debugging on the core dump from the last crash. It looks like the crash is this assertion failure in libepoxy: "Couldn't find current GLX or EGL context." https://github.com/anholt/libepoxy/blob/1.5.4/src/dispatch_common.c#L863 The proc being looked up is glDeleteProgram. The only call to glDeleteProgram() I see in kwin is in ~GLShader(): https://github.com/KDE/kwin/blob/v5.20.3/libkwineffects/kwinglutils.cpp#L159 I'm guessing the screen/display is disappearing when it turns off/sleeps, and when stuff gets torn down the destructors try to touch a GL context that isn't there any more. -- You are receiving this mail because: You are watching all bug changes.
