This bug was fixed in the package mutter - 45.2-0ubuntu3
---------------
mutter (45.2-0ubuntu3) mantic; urgency=medium
[ Jeremy Bícha ]
* Revert roll back to 45.0-3ubuntu3.1
[ Daniel van Vugt ]
* Update Support-Dynamic-triple-double-buffering.patch
with a fix to the frame clock for a regression inherited from
45.1 (8f27ebf8) whereby it would enter triple buffering mode
prematurely. And because it was premature, the clock would soon
notice that triple buffering isn't required and drop back to double
buffering. But the switch from triple to double buffering stalls the
client frame queue by one frame which for some clients like Firefox
is seen as a frame skip. (LP: #2046360)
mutter (45.2-0ubuntu2~really45.0) mantic; urgency=medium
* Roll back to address regression LP: #2046360.
- Full revert to mutter 45.0-3ubuntu3.1, with revert implemented under
debian/patches to avoid having to keep around confusing version numbers
for very long.
- mutter 45.2 introduces new library symbols vs 45.0 but no packages
have picked up dependencies on these symbols yet via rebuilds, and all
binary packages built from mutter source have a strict versioned
dependency on the library package; so a straight revert of the symbols
file is possible without the need to add any additional Breaks.

* debian/libmutter-13-0.symbols: Add new symbols

* Rebase X11 fractional scaling patch
[ Daniel van Vugt ]
* Rebase triple buffering patch
