My Brush Panel Thumbnails are Scratchy and Distorted [OSX Mojave — CS5]
Product: Adobe Photoshop CS5 on my iMac OS X.
Out of nowhere my brushes aren't showing in the thumbnails like it'd normally would. Every time I open my brush menu now, instead of seeing images of the brushes I get these scratchy squares of static. This goes for new free brushes I upload as well. And it's not just my brushes, the pulldown buttons are scratchy too. I'm certain it has something to do with my updating my computer to Mojave (WHICH I TOTALLY REGRET!), since it's been creating other problems with software. I tried everything I can think of from returning to factory settings, resetting the tool, resetting the brushes, and quitting and restarting Photoshop again. The image I attached is what I'm dealing with. I don't know what is causing this or what to do. Is there anyway to fix this?
P.S- I can see more of the brushes in the Brush window that would appear on the right if turned on, but not all of them, the scratchy boxes are still there. Also it would seem every time I click on a thumbnail in the brush window it turns to static like the others until I click away from it.
Any help would be appreciated
