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!

The red square covers the entire screen. I am not very tech savvy so I am not sure about the file types causes it. Most of my images are JPEGs and WebP. The red square effect happens at random, maybe 1 out of 10 times I use quickview.

Hey there!

Wow that’s a strange one! Does it cover the entire screen? Likewise does this happen when previewing images in Quick Look for every file type and from any location?
