Are you all on gnome-shell? I have the same transparency issue in gnome- session-flashback / lightdm, but only when using theme Ambiance. I moved to theme Adwaita and the transparency issues are gone.
Setting the input method to iBus does fix it for theme Ambiance too. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to im-config in Ubuntu. https://bugs.launchpad.net/bugs/1760818 Title: gedit and gnome-calculator transparency/graphics corruption issue when GTK_IM_MODULE=xim is set Status in gtk+3.0 package in Ubuntu: Confirmed Status in im-config package in Ubuntu: Confirmed 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.
