Hello. My Maya 2023 began to have a strange issue where the viewports are black partially. It's almost as if I was using 4 system viewport but I'm not really. This issue wasn't with my maya from the start, it just started out of nowhere and won't go away. Everything works fine besides this visual issue. I'm a student and not very tech savvy either. Could someone please help me figure out how to fix this. Thanks in advance!
