Glitching Cover Art

Ever since I updated to iTunes 12.2.0.145, the cover art of all my music disappears/reappears whenever I scroll a little too fast. When I select 'Songs' instead of 'Albums,' the cover art there does the same thing, but even worse (the art disappears for seconds at a time with only a little scrolling). I thought it was a little bug with the new update that would disappear after a few days of use, but it hasn't yet, and that was nearly a week ago. I've tried restarting iTunes, my computer, and even deleting and adding the artwork to the music again. Nothing is working. Is there any way to fix this?
