Photoshop renders artboard grey when Photoshop is unfocused

[hpmueller]

Photoshop version: 21.2.0

OS: macOS 10.15.5 (19F101)

Since the 2020 update Photoshop renders a grey artboard whenever the app is unfocused. The grey artboard problem also appears when moving objects around, but only sometimes and not really reproducable.

I made a screen recording of the issue: https://youtu.be/RovT82FC3J8

Any suggestions?

Seems related, changing settings under Preferences didn't solve the issue, deleted preferences didn't either.

Hi, I think is a known temporarly issue due to some graphic card drivers.
