My screen sometimes turns negative/inverted in colors when I hit a dialog / end-of-actions. The most obvious one is when I have no more steps to undo in PowerPoint of Excel and press CTRL+Z again my screen shows inverted / negative momentarily, ca. 1 second. See below.
Any idea if that is an error or setting? I would like to get rid of it.
Windows 10.0.19044
So picture 1 is normal, picture 2 is inverted.

The comment given by Tetsujin gave me the right terms to Google on. Found a post that explained:
Go to Control Panel > Easy of Access > Replace sounds with visual cues
There you can configure / disable it.
