--- Comment #3 from Roman Gilg <subd...@gmail.com> --- Created attachment 124538 --> https://bugs.kde.org/attachment.cgi?id=124538&action=edit poc patch I can reproduce on Intel. The issue lies in the swap event not being registered correctly after compositing went down while a page flip is ongoing (probability for that high when often changing content on the screen like a game). Please compile KWin with the attached proof-of-concept patch and see if that solves the issues for you. -- You are receiving this mail because: You are watching all bug changes.
