WindowServer 100%+ CPU usage

Updated to BigSur 11.5.1 and WindowServer is bogging my computer down. I usually monitor the processes on the machine pretty carefully and I have never seen WindowServer stay this high this consistently. Any idea about why this is happening?

MacBook Pro 15″, macOS 10.14

window server high cpu on Monterrey Hi, All every since latest upgrade to Monterrey (on 12.1) I have been seeing this windows server issue that many have reporterd over time and CPU is going mad and fan when literally barely anything running. I have took all the advice on most threads, virus checked, removed old software no longer in use, changed display settings etc and none of it works and still it goes on. Safari starting literally makes it worse, so much so had to switch to FF and even then barely improved matters. Can somneone please help as this is driving me mad !! Cheers, Ian

Why is Report Crash using 98% of my cpu? My MacBook Pro, running 12.0.1 os, with 8GB of memory is running very slowly. The Activity Monitor shows that 99.6% of my CPU is "Report Crash". I can't close this process. What can I do to speed up my laptop?
