Hi,
Thank you for the package in -proposed.
I just tested Ubuntu 22.04 and I can confirm it fixes the issue.
First, used 22.04 with the current mutter version available in jammy-updates:
user0@U- 2RVWD6LKXR3GE: ~$ sudo apt-cache policy mutter-common libmutter-10-0 gir1.2-mutter-10 sa-east- 1.ec2.archive. ubuntu. com/ubuntu jammy-updates/main amd64 Packages dpkg/status sa-east- 1.ec2.archive. ubuntu. com/ubuntu jammy/main amd64 Packages sa-east- 1.ec2.archive. ubuntu. com/ubuntu jammy-updates/main amd64 Packages dpkg/status sa-east- 1.ec2.archive. ubuntu. com/ubuntu jammy/main amd64 Packages sa-east- 1.ec2.archive. ubuntu. com/ubuntu jammy-updates/main amd64 Packages dpkg/status sa-east- 1.ec2.archive. ubuntu. com/ubuntu jammy/main amd64 Packages

And I do hit the error when trying to revert after changing the scale:

Then, I upgraded to package from -proposed:
