Comment 0 for bug 1923075

In Ubuntu 21.04 beta (using the wayland session) when unmaximizing a window by dragging it off from the top bar at least two bugs happen randomly.

1. The window might not unmaximize at all but keep it's maximized size.
2. The unmaximize animation does not play correctly (only "slides" but does not "scale").

Note that unmaximizing by using the maximize button or alt+f10 works correctly.
Also X applications such as xterm unmaximize correctly when dragged of the top bar.
