And I have the same issue.

Title:
Changing display scale setting and reverting it, causes gnome-shell to
error with "Failed to restore previous configuration" and other error
messages
Status in mutter package in Ubuntu:
New
Bug description:
In Amazon Workspaces running Ubuntu 22.04, when attempting to change
the Scale in the Gnome Display settings, if you click on a different
scale (i.e. changing from 100% to 200%) and hitting apply, it will
bring up a prompt asking if you want to keep or revert the changes and
there will be a timer of 20 seconds. If you try to revert the changes
(either by letting the timer expire or by clicking the "revert"
button), we will hit one of the following two behaviors:
1 - The setting won't revert and will keep scaled
2 - gnome-shell will show some error messages in syslog and the
display will be "corrupted", where the only window you are able to
click is the display setting and if you try to drag it, it will leave
a "blur" throughout the window (per discussions, this seems to be
https://launchpad.net/bugs/1924689)
For both situations, changing the display resolution (i.e. going into
and out of full screen in the workspaces client) will fix the issue
When hitting situation 1, syslog shows:
May 17 17:33:10 U-1AZMIM8SIPZ6I gnome-shell[3030]: Failed to restore
previous configuration: Invalid mode 1920x1080 (19.958942) for monitor

I'm unable to reproduce the problem if I manually install ubuntu-desktop and
use the Nice DCV Server (as used by Workspaces) by following the steps from
(using the xorg-x11-drv-dummy):
https://docs.aws.amazon.com/dcv/latest/adminguide/setting-up-
installing-linux.html
One relevant difference is that Workspaces uses a custom X11 server
/usr/bin/Xdcv, instead of /usr/lib/xorg/Xorg, and they have the
following process being started:
/usr/bin/Xdcv -output 800x600+0+0 -output 800x600+800+0 -output
800x600+1600+0 -output 800x600+2400+0 -enabledoutputs 1 vt2 -displayfd
3 -auth /run/user/541001128/gdm/Xauthority -nolisten tcp -background
none -noreset -keeptty -novtswitch -verbose 3
I'm also unable to reproduce the problem using xrdp + Xorg.
While discussing this with the desktop crew, it was mentioned that we see the
same problems in
Xorg. And to a much lesser extent some issues in Wayland too when changing
scales.
