https://bugs.kde.org/show_bug.cgi?id=3D328242 --- Comment #10 from Thomas L=C3=BCbking --- I assume it's related. The driver will likely somehow "fake" the second cursor into the frontbuffer from where we (invalidly) read it back for the next frame. This should simply be gone with GLX_EXT_buffer_age preference. --=20 You are receiving this mail because: You are watching all bug changes.=
