Hey, Daniel! You sent me here from #1890281 #1725649 is said to be fixed but the bug is still present on Ubuntu 18.04.4 running X. I've recently upgraded to Bionic and noticed this bug immediately as I often play games.
Shall I file a new bug report? Thanks in advance. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1732245 Title: Fullscreen game windows vertically offset after returning from Alt-Tab Status in Mutter: New Status in mutter package in Ubuntu: Confirmed Bug description: Impact ====== Using Alt-Tab to leave a fullscreen game and then return breaks the game by offsetting the display by the size of the GNOME Shell top bar (and the Ubuntu Dock if running). Test Case ========= 1. Log into the default Ubuntu session. (Make sure that Wayland is running by running this command. If you have output, you are running Wayland. env | grep -i wayland 2. Run a game full screen. I installed Steam and used Team Fortress 2 because it's free (but a very large download) 3. Press Alt-Tab to switch to another window and then press Alt-Tab to switch back to the game. The game should display and function normally. Workaround ========== Open the Activities Overview and click the game window instead of using Alt-Tab to switch back to the game. Other Info ========== This bug is split from LP: #1725649 where the problem was seen and fixed for the Xorg session. This bug is for the Wayland sessions.
