You already tried reinstalling CInnamon but can you try it by purging this time, if you already didn't do it like that?

sudo apt purge cinnamon
sudo apt autoremove
sudo apt install cinnamon cinnamon-settings cinnamon-session cinnamon-screensaver

Then reboot.

This seems to be an error that traced back to Mutter, since Muffin (CInnamon's window manager) is a fork of it I believe they are related. Maybe an upgrade solve this? The post says you are on 21.3, so while on TTY, do an upgrade to see if that works.

sudo apt dist-upgrade

Similar thing happens to me with my two monitor setup. No problem when I use single monitor. No problem when I use two monitor. However when I plugged out the second monitor or switch to single monitor with my script, the CPU starts doing random spikes on single cores in short intervals. Only a reboot fixes this.

No problem! My first switch to Wayland was with Hyprland. It's very fancy and I see how this tool can get along with it quite nicely. Though I was a Bspwm user and switched to River recently. I usually only see my wallpaper when I first boot the system and if I want to run a non-automated program. But still even for me this can be useful when I work with two monitors.

Would this run on River by the way? Since River handles workspaces a little differently.

That's an interesting way to put it. I like how everyone does different things on their workspaces and some of them can be pretty clever. :)

Neat! Though if you're using a tiling WM, having a wallpaper is kinda useless.

I see. Personally I have no concerns since I don't even use G-apps at all. However I don't want anyone to come to me with a problem either, which currently none I believe.

I install custom ROMs on every device in my household. How concerned should I be? None of them are rooted. Would disabling Play Integrity via adb fix this?

Go to a TTY by pressing Ctrl + Alt + F3. Replace F3 with F4, F5, F6 etc if you are already on that TTY. Once you are in TTY, login with your user and its password. Then run cinnamon --replace. If it runs without any problems, the problem might be related to your display manager. If it doesn't start, you should see the errors.

You can try to start Cinnamon on TTY to see what goes wrong.

New Empire Earth looks great too.

Unless there is a raccoon involved. Then it's both.
