[SOLVED] GNOME 48/NV Fractionally-scaled Monitors constantly freeze

I upgraded my NVIDIA machine today, and am now on GNOME 48. I have three monitors. My first monitor is scaled to 175%. My second monitor is scaled to 100%. My third monitor is scaled to 150%. Whenever I move my cursor on a fractionally-scaled monitor inside many applications (Firefox, GNOME Control Center, Chromium, Alacritty, Console), it freezes for a few seconds, and then unfreezes. If I don't move my cursor at all and only initiate UI changes using my keyboard (e.g. changing to another tab with Alt+5), it doesn't freeze.

Some applications don't freeze, like Steam, Krita, and games I attempt to play. These seem to be XWayland applications.

On my 100% scaled monitor, no applications freeze at all.

I found that setting my primary monitor to 200% instead of 175% would prevent major freezing, but I still suffer stutters (mostly minor, sometimes freezes up to half a second like when switching workspaces).

I've been using fractional scaling on GNOME successfully for over a year now, so there appears to be a regression.

I didn't find much useful in journalctl.

Downgrade mutter to 48rc and see if that helps.

That did it! No more freezing after running this and logging back in:

sudo pacman -U https://archive.archlinux.org/packages/m/mutter/mutter-48rc-1-x86_64.pkg.tar.zst
