I was getting some inconsistent and confusing results on my tests, so I decided to start from scratch with a fresh VM (qemu) and also a fresh Workspace (AWS).

In a freshly installed Jammy VM (on qemu, not AWS), out of the box we have factional scaling disabled, so I tried changing scale to 200% and I do hit the error (but the scale DOES change):

When I try to revert, I hit the error again and gnome freezes:

I then upgraded the packages in the PPA:

sudo add-apt-repository ppa:vanvugt/mutter
sudo apt update
sudo apt upgrade

Rebooted the VM

When I still hit the error both when trying to change the scale to 200% (still does change it, though):

https://pastebin.ubuntu.com/p/V7MmKCjc4W/

And also when trying to revert it (gnome freezes):

Also did the same tests with a fresh Workspace:

Tested the very same thing in a Workspace:

Out of the box fractional scaling is disabled, so I tried changing scale to 200% and I hit the error (but it does change):

When I try to revert, I hit the error and then it causes the problem reported in https://launchpad.net/bugs/1924689:

https://pastebin.ubuntu.com/p/NHY62YvxCG/

(So both Workspaces and local VM hit the same problem, but when reverting Workspaces will hit LP#1924689 and the local VM will freeze gnome)

I then rebooted the Workspace without upgrading any package and tried the same steps again, and I still have the same problem.

I then upgraded the packages in the PPA:

sudo add-apt-repository ppa:vanvugt/mutter
sudo apt update
sudo apt upgrade

Rebooted the Workspace, and I still hit the error both when trying to change the scale to 200% (still does change it, though):

https://pastebin.ubuntu.com/p/977wzx6sxW/

And when I try to revert:

https://pastebin.ubuntu.com/p/D2VZv2J7QV/

Packages:

So, unless I'm missing something, apparently the same problem happens with fractional scaling disabled and also with the packages from the PPA.
