I experienced this bug today. Restart didn't help initially. Then I changed the Input Method from xim to ibus and the problem was gone. Changing back to xim did not bring the problem back. I'm confused that it worked. Would be nice if somebody else could try the same.
I did not install any new packages, neither did I re-install any packages. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-themes in Ubuntu. https://bugs.launchpad.net/bugs/1760818 Title: gedit and gnome-calculator transparency/graphics corruption issue Status in im-config package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Status in ubuntu-themes package in Ubuntu: Invalid Bug description: In a "Ubuntu" (Xorg) session on 18.04 gedit and gnome-calculator suffer from a graphics issue where parts of their windows hold parts of wallpaper or other windows' contents as background.
