Thanks. It's very strange that the dimensions of neither image match actual screen resolutions. I guess that's one possible reason why they're not staying full screen -- the window size is not supportable.
Another issue I notice from your screenshots is the unusual panel and icons hanging down. This makes me think you might be using some extensions(?). Please try uninstalling all gnome-shell extensions, reboot and retest. We need to uninstall extensions and not just disable them because broken extensions might also fail to honour the disable request. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, 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...
