Bug#1093876: mutter: include additional triple-buffering fixes from upstream

[Christopher Obbard]

Source: mutter
Version: 47.4-1
Severity: important
X-Debbugs-Cc: obbardc at debian.org

Dear Maintainer,

I was having a problem with mutter where the framerate drops
significantly after a while. This was discussed in the upstream bug
tracker and a fix for the triple-buffering patchset was made:
https://gitlab.gnome.org/GNOME/mutter/-/issues/3880

This patchset need to be refreshed in the debian package to include
these changes.
