That won't be needed :)
I've did a quick and dirty packaing of upstream'S 515.76 driver [1],
and this driver does not show the garbling, evenwith NVreg_PreserveVideoMemoryAllocations
turned on. This is consistent with a comment on the nvidia forum (see forwarded
link, response 16) saying that they have adressed the issue.

Yes, I know... When I first had the issue with Gnome being ugly to unuseable in
Jan 2022, it took me quite some time to figure this out eventually find the
solution… So I wonder if it would be actually be better, if enabled by default?
The bug in Ubuntu - https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1876632
shows that this affects quite some people…

[1] Went surpisingly smooth. Kudos for your packaging work!
A patch, module/debian/conftest-verbose.patch was not applying, and it seems
that there is no longer a library for lib${nvidia}-nvvm4 and I had to add one entry
to nv-readme.ids, and basically then it built :)
