I wonder if the delay is equal to the number of buffers' whose damage mutter is tracking... What this means is that it could take 3 or 4 frames to update everything. I've seen reports of such issues in mutter 3.34, like bug 1845623.
If you have a separate window animating in the corner of the screen (glxgears or a video) then does that work around the problem? How about if you have a maximized window constantly updating underneath? ** Changed in: mutter (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1846201 Title: Rendering is delayed on laptop display (works in external display) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1846201/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
