Windows 10: Black rectangle afrer apparent screen glitch

I don't have a screenshot but sometimes when I'm on video calls, specifically google meet, my screen will glitch out, showing a white dotted screen with red and blue and white dots before a black rectangle appears that goes away when I open tasks manager. So does anyone know if it's just google meet or something else? My anti-virus software hasn't picked anything up.

Black rectangle shows up middle of screen- mouse doesnt work within it

Since my last post, the box has reappeared but Photos was not in the list. Today, I closed one of two entries called "system" and it went away. Btw, fwiw, Winlister mentions several programs are open that arent open and havent been opened since last reboot, like calculator.
