High WindowServer usage on Sequoia Beta 2

[underscoregeb]

Description

I'm seeing excessive CPU levels (up to 90%) from WindowServer while Swift Shift is running. This comes with poor system performance and low frame rates. It usually occurs anywhere from 10 to 30 minutes after Swift Shift is started. The issue persists in macOS Safe Mode.

I'd be happy to provide logs, but i'm not sure the best way to get them.

Environment

MacBook Pro with M1, macOS Sequoia Beta 2 (24A5279h) This may or may not be related to the beta, as I installed Swift Shift for the first time after updating to sequoia. (wonderful app, by the way!)

Steps to reproduce

• Start Swift Shift
• Wait up to 30m
