Thanks for info. FYI I now workarounded the problem using x11 instead of Wayland (it's sad that deprecated x11 which is to be removed works and new Wayland replacement not). > Does the problem also happen for you with the proprietary NVidia driver? > Nouveau is unfortunately still known to be more buggy than the proprietary > driver. I'll try to test it with some Linux live distribution which ships proprietary NVidia driver and let you know (I suppose it works otherwise you'd get other bugreports already but who knows). But I'm not going to use proprietary NVidia drivers (bring other problems). I'd prefer to know how to give useful bug reports triggered by kwin/KDE to nouveau developers to help the problem fixed instead of relying on proprietary drivers. Maybe I try to test running kwin on Wayland with: KWIN_DRM=1 LIBGL_DEBUG=verbose kwin_wayland --xwayland --replace (None of previous variables are in https://community.kde.org/KWin/Debugging). Or any other suggestion how to debug? Can it be caused by OpenGL initialization by Nouveau? Or is it more likely the kernel driver itself? Also GNOME mutter works with Nouveau on Wayland seamlessly, I wonder whether they workarounded bugs. -- You are receiving this mail because: You are watching all bug changes.
