Something I've discovered so far: If the monitor is scaled up it has a chance that the active region and the background drawing region is unchanged, causing glitches like broken shadow, as well as unclickable UI elements outside the original box.
This might have something to do with detecting changes of the window dimensions due to scaling. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1924689 Title: Window border corruption after changing display scale between 100% and 200% in Xorg Status in Mutter: New Status in OEM Priority Project: New Status in mutter package in Ubuntu: Triaged Bug description: Ubuntu release: Ubuntu 20.04.2 LTS Issue description: When the gnome-initial-setup launched, if user changes the scale 200 -> 400 or 100 -> 200.
