macOS Monterey Beta 4 Extremely Slow?

I was not around yesterday so I didn't use my Mac mini, but rebooted 12 hours ago and today Window Server has been sitting around 20% usage as opposed to 100%. The entire Mac feel SO much better. I don't see anything about a new public beta so I'm not sure what changed. This is not the first reboot I've done; which is strange why now it seems to be fixed.

Not sure what CPU usage WIndowServer usually uses.
 
the only thing is boot time is slow I am running Vivaldi browser and it is extremely fast

Same issue here on 16" MBP both on battery (integrated) and plugged in (discrete) with/without a 4K display attached. Also very bizarre that Caps lock seems to exacerbate it.
 
I definitely have this issue as well. I've noted Spotlight taking up 50-70% CPU util. at any given time; disabling it via terminal doesn't seem to help.
 
No such performance issues as described here on b4. Fresh install b4 from scratch, manually migrated data, red-downloaded apps. Intel i9 10900K, running well. Nothing particular of concern other than Mail.app give an error trying to import mbox or mail archive, it thinks nothing has been selected in the list.

Ever since updating to macOS Monterey Beta 4 (from Beta 3) my entire computer has felt extremely slow. Switching window focus, typing and having a major delay before letters show up, etc etc.

According to Activity Monitor, WindowServer is taking up 80-110% CPU consistently.

Has anyone else run into this?

I'm having the same problem after updating to Beta4! I thought at the beginning, it was a browser problem (because specially the browser was slow), so I switched from Brave back to Chrome, back to Firefox, back to Safari, and all of them became slow after 2-3 days of use.
Memory management looks alright, but WindowServer is particularly heavy on CPU usage, but never over 50%. I don't remember if it ever was that high though.

EDIT: Running on M1 Air, 16G RAM
 
WindowServer gets stuck after connecting to external monitor. Restart solves it.
 
I posted this on another post but thought I would post here also as original was related to browser slowness. I was having similar issues up until today and then did some research and found that others were having high CPU with the windowsserver process. To clear the issue I reset the NVRam that someone else suggested and since then MS Edge has not been having any issues where as before I was getting slow response and beachball quite often. At first I thought it was one of the extensions and started removing them without any success. Since doing the NVRam reset and things have been working normal and I have reloaded all my extensions without issues.
