There are other cases, I'm going to leave the link here to better document the problem.

Small white rectangle appearing on upper left side of RStudio, what the heck!!??

Hello, A small white rectangle appears and disappears, seemingly randomly, in the same location in RStudio. I've been a user for years and have never seen or heard of such a thing. Also, I cannot find anything about it on the web. Has anyone seen this or know how to get rid of it? [image]
