I spent a day on Wayland, and I found that parts of this bug are present on Wayland, though somehow less frequently, I could only trigger them with screen scale changes. Not all apps seem to be affected equally, but I can trigger it reliably with the Signal, Slack, git gui or gitk apps. Signal and Slack are snaps, git gui and gitk are installed via apt. Open the app, change screen scale from 200 to 100 or vice versa, see the mess. Scaling from 200% to 100%, these apps get a defunct window decoration that is out of sync and size with their content, the texture buffer is apparently full of random garbage that fills the holes. The effect is slightly different, depending on whether the app had been started at 100% or 200% screen scale.
