I've discovered a glitch in Lightroom Classic and can reproduce the issue each time. I'm using a 2021 MacBook Pro with M1 Max. I'm using Lightroom Classic Version 11.1 and macOS Monterey Version 12.2.
In the Develope Module, expand the Transform panel on the right. Then expand the Masks panel. When you hover your cursor over the Transform panel, the entire panel will start shaking / glitching. When the Masks panel is closed, the issue is resolved.
Please see the video below showing this issue occuring.
