x11-wm/mutter: update patchset
Includes more commits from upstream gnome-3-30 branch, a patch
to hopefully fix an on_monitors_changed related crash I'm
experiencing once in a while myself (when monitors go to sleep
and wake up from screen lock). Also includes some patches
debian/ubuntu include, more prominently support for native
refresh rate on wayland sessions (not hardcoded to 60Hz),
workaround for startup-notification problems (fixing e.g.
gnome-terminal appmenu spinning until a timeout, when really
g-t has long started), fix for limited memory old GPUs and more.
