Invalid <face>. > Invalid framebuffer status: "GL_FRAMEBUFFER_INCOMPLETE_MISSING_ATTACHMENT" Obviously, that's not supposed to happen, and we should fix it. A possible cause could be that KWin attempts to use the cursor plane each frame, which can possible cause memory allocations that can afaik be pretty expensive on Nvidia because of some driver / firmware limitations. If you set https://invent.kde.org/plasma/kwin/-/wikis/Environment-Variables#kwin_force_sw_cursor to 1, do the warnings go away? Also, if you're modifying KWin already, you could test https://invent.kde.org/plasma/kwin/-/merge_requests/8926, which may avoid issues the OpenGL path has. -- You are receiving this mail because: You are watching all bug changes.
