I found a work-around: disabling animations in GNOME Tweaks solves the issue and the whole Top Bar (not a ghost of it) and the Dock are visible for a very short time until the window becomes fullscreen.
I suggest to include an option to disable these animations when fullscreen windows are present because they also cause frame drops. As for upgrading I'm patiently waiting for the dot release. Fingers crossed tomorrow is the day. :) -- 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.
