Thanks. The only strange graphics-related issue I can see is that this system has 22 (twenty two) known monitor layouts stored mentioning dozens of different monitors. It's a mess and could easily cause this bug. Please try moving the file ~/.config/monitors.xml to a different directory and restart the system. You might then need to reconfigure the monitor layout in Settings.
If the problem reoccurs then next please run: xrandr > xrandr.txt and then attach the file 'xrandr.txt' here. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1859774 Title: Full screen window becomes "small" in the upper left of the screen... Status in gnome-shell package in Ubuntu: Incomplete Bug description: This happens with a number of different programs, so I suspect it is a window manager bug. The best way to describe it is with a screen shot. The only responsive part of the screen is the small window in the upper left. You can hit the little maximize box and it goes back to full screen okay, but after a while it comes back to this. It can be annoying, because sometimes you can't quickly see what happened to the title bar. I'm using Ubuntu 19.10. This has been happening for about a week.
