Alt-tab misbehaves with fullscreen windows
Tested with 3.34.1, and has always exhibited this behavior, as far as I can remember.
If I wish to alt-tab away from a full-screen program into a non-fullscreen window, the fullscreen window stays on screen (even though the focus is on the non-fullscreen window). To properly see the non-fullscreen window, I need to alt-tab again to it.
The reverse is also an issue. If I wish to focus on the fullscreen window, alt-tabbing to it will show it, but will also show the gnome panels (the fullscreen window has focus). To make the panels disappear, I need to alt-tab again to the fullscreen window.
Sometimes when I launch fullscreen programs, they start with the gnome panel still visible.
To see an example of the first two issues, here's a free game to test this with. In the dialog that pops up, make sure you choose to start it in fullscreen (the default) and not windowed.
For comparison, I tested this with Gnome Classic and got a different behavior:
- Alt-tabbing from and to fullscreen window works the first time - this is good!
- Alt-tabbing away from fullscreen window shows the non-fullscreen window, but doesn't show the desktop panels - this is undesired.
