I had the same issue. I found root cause of this problem. It is Dell Display Manager app which I used to manage screens and windows. When I close this app permanently this problem never came back.

Sounds like two issues. WindowServer and a memory leak. We were having the WindowServer runaway CPU usage - took a lot of trial and error but for us getting all things Google off the computer (to include Keystone) helped a little WindowServer down into the 20-30% range from over 100%. In the end the more significant culprit was found to be Sophos Home. Removed Sophos and WindowServer is consistently back to single digits - also improved the Watt draw and temps of the laptop noticeably.

Reading some more - there might be another issue causing your issue.

If one has changed the Default Curser to Red - there are reports that this may cause the issue being experienced.

If this is your case - suggest putting it back to the Default setting and then, Test if the " Windowserver " issue is resolved.

I have the same issue on my 2021 MBP. Windowserver sometimes uses up to 107% CPU and almost 15 GB RAM, the MBP gets really hot and the battery drains really fast. The only temporary solution is to restart it as you said and it's getting really annoying.

1 - No Time Machine backup - Time Machine backup not found.

Ans - A Time Machine Backup  is very useful and can be used to Revert to Previous Working macOS

2 - x86-only Apps - This computer has x86-only apps might not work on future versions of the operating system.

Ans - Although they may function by invoking Rosetta 2 - it might be worth the effort to explore newer Universal Application that do not required depending on Rosetta 2.

3 - /Applications/Bitwarden.app/Contents/Library/LoginItems/Bitwarden Login

Ans - https://bitwarden.com/download/ According to their website it support up to Mojave macOS 10.14 and no specific mention of Monterey Compatible.

Ans - Could not find any information specific to what version of macOS is supported.

My Macbook M1 pro 16" went from 1gb in windowserver to 90GB on windowserver on 3-4 days. Then it gave me the notice of not enough memory left. I'll try this one, hopefully it works

Advise as been offered and done so in good faith.

What is done, at this point, is up to the user.

Yes, Antivirus Software installed for a Non Existing Issue is money down the rabbit hole and zero return except endless headaches and possible Reinstallation to put thing right again.

The resource draw of all things Google (even when chrome wasn't running) was an eye opener also!

Have you changed the cursor colour and/or size, if so reset back to the defaults and see if it resolves the problem. I know it sounds absurd but this has been found to resolve memory leaks. Hopefully a fix will happen in a future update.
