Bug Description

When mutter was upgraded to 3.26.1, maximising windows in gnome-shell (xorg session) and budgie-desktop and subsequently closing those windows causes the window manager to crash;

after a couple of times the whole session crashes and you are left at the login prompt.

This is a known issue upstream:

Note: under budgie random crashes of the desktop have been observed:

These have been traced back by budgie upstream to the same bugzilla issue above.

We have tested the suggested fix in the bugzilla report and can confirm that both the gnome-shell (xorg) session no longer crashes and (for us) the instability issues with budgie desktop are no longer observed.
