Strange Artifacting in FCP

Ok, 2013 iMac 27" with the i5, 32GB RAM, GT755M running Sequoia 15.4. As of yesterday I've noticed that while running Final Cut Pro I get artifacting showing up primarily in the View window and in random thumbnails on the timeline.

I've been using this on Sequoia for about a month now and it only started last night. I'm hoping there is an option I need to deselect in the option features and that it's not my GPU on its way out.

Any help would be appreciated. Thank you!
