https://bugs.freedesktop.org/show_bug.cgi?id=104598 --- Comment #5 from Michel Dänzer --- I can't reproduce this, is it still happening for you? Is it with vkmark in fullscreen or windowed mode? Which version of kwin, and what's selected for rendering method and tearing prevention in kwin's compositor settings? Also, please make sure kwin isn't using the EGL backend. -- You are receiving this mail because: You are the assignee for the bug.
