OK, at scale 100% then this would not be a shell bug. Applications always have the final say in what size their windows are and then shell can't enforce otherwise unless it wilfully displays the window at the wrong size. You would notice if the window contents provided by the app don't fit in that case...
That said, maybe the apps are still willing to resize better in this case and maybe it is the 200% scale that is a problem with gnome-shell. -- 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/1806279 Title: No full screen possible when the minimal window width is higher than the horizontal resolution Status in gnome-shell package in Ubuntu: New Bug description: As described above. If I rotate my laptop and want to use it in portrait mode, I can only use the Gnome Calendar to a very limited extent, because e.g. full screen is no longer possible.
