Thanks for the quick response! Another detail I want to add is that it only happens after invoking the switcher. I can control volume or screen brightness all good without any problems but as soon as I switch windows and go back to my game the top bar keeps appearing whenever the volume or screen brightness controls are accessed. The switcher is definitely the culprit here.
It happens on X, it happens on Wayland. On X, the bar usually disappears as soon as the switching animation stops or volume and screen brightness control pop-ups fade away. On Wayland, the bug persists until I re-open the affected window through Activities, not the Switcher. GNOME Shell 3.28.4-0ubuntu18.04.3 Mutter 3.28.4-0ubuntu18.04.2 -- 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.
