That's because some app is spamming window updates.
It's been an ongoing problem for many releases. AFAICT, WindowServer 100% CPU is a symptom, not a cause.

But apps shouldn't be able to hammer WindowServer in the first place. If your app is misbehaving, your app should hang, not the OS window compositor!
FWIU there's really no backpressure mechanism for apps delegating compositing (via CoreAnimation / CALayers) to WindowServer which is the real problem IMO.
And I could imagine SwiftUI only makes this worse, because it's quite easy to trigger tons of unnecessary redraws.
People don't really like apps that stutter.
And maybe that would get enough users to leave or complain that managers might allow some dev time to fix bad behavior.
Symptoms with no way to understand why.
If Apple would give insight about this, the developers wold get bug reports and complaints
