GNOME 40 wayland-session exiting fullscreen doesn't restore original size & position

[Lukas Wiest]

Switching applications between normal and fullscreen got slower and also it won't remember position and size of the window on exiting fullscreen compared to gnome 3.x.
I can also confirm this on a 20.04 installation with gnome 40 installed, that this is a degradation for gnome-shell 40 on wayland sessions. Xorg session is working fine.

I've tested this with
- firefox (F11 to enter/exit fullscreen)
- YouTube videos
- eog

On going to fullscreen it often looses focus, and on exit the window just gets resized to the full monitor resolution.

Rolling back my 20.04 machine to gnome 3.36 will make this work again under wayland.
Considered that gnome 40 is the default for 21.10 and also wayland is the default, I hope this get's investigated and a fix is found before 20.04 is EOL.

This will be fixed in gnome-shell 40.6 by:

commit aded2cd01b7af4d2bf355ed7cb129c6b869d84fb

    Revert "layout: Exclude hidden actors from struts"

    The change unvealed a series of mutter bugs that for most
    users are worse than the issue that was fixed. So revert
    the change on stable branches until the mutter side is
    fixed.

    This reverts commit cd1102ff30b134e45e9b5ab48318e6a4eae03416.

I look forward to this fix. The problem also manifests when unlocking. Sometimes it gets stuck in a loop where the screen keeps flickering as elements resize, until I switch windows. Quite annoying and common in default 21.10.

[Daniel van Vugt (vanvugt)]

The fix for GNOME 40 and 41 is in gnome-shell per comment #3.

The fix for GNOME 42 is in mutter instead, and just landed: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2066
