I guess I should add that this is caused by SDL hinting that the compositor should be disabled even when the game is running windowed. I've unchecked "Allow applications to block compositing" awhile ago and forgot I even made this ticket.
I do still occasionally (once or twice a week) get accelerated applications failing to redraw, but since either 19.10 or 20.04 this only happens at the application level instead of the whole desktop and simply restarting the application (or dragging the tab to a new window in Firefox) works around the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768693 Title: Display flicker when starting/stopping SDL2 game To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libsdl2/+bug/1768693/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
