Weird issue I found: when I tried to open my post history by clicking on my username in the top right, the background of the tooltip is transparent!
works for me, turning off ublock makes a difference? iirc they have a rule that removes all backgrounds on our site
Oof, looks like I found the same thing.
I'll try it.
Update: Yes, it works. I'll make an exception for the site in uBlock Origin, but is there anything the devs can do?
Update 2: Turning off cosmetic filtering in uBlock Origin fixes the issue.
