I've been seeing this problem lately where the Open dropdown menu in the Collections panel flickers wildly (scrolling madly up and down by what appears to be one page worth) and I cannot select anything from it because I can't tell what I'll be clicking on. I don't have a 100% reproducible case, but it seems to happen when I've been messing around with creating new collections and/or deleting them. It only started happening in a recent beta (I think 10 or 11 or 12; can't remember when).
Here's a video showing it:
