Red square covers screen when I preview images on MacOS Monterrey 12.3

I recently updated my 27" iMac to Monterrey 12.3, when opening images in quick look a giant red square covers my screen for a solid second.

Hey again! Good to know it’s random. Others may know a more specific resolution if they’ve seen this, but I would suggest testing the issue in Safe Mode, and/or in a new user account, this may help to narrow down a cause:


Start up your Mac in safe mode - Apple Support


Set up users, guests, and groups on Mac - Apple Support


Hope something here helps!
