here's another video confirming it on another hud as far as the class selection goes. when the bounding box of the class element overlaps with another class and you hover in the shared area, it causes the issue (as you stated)
I wonder if the animation itself freezing up has anything to do with it; when you idle between two classes, the animation also doesn't play properly
edit: stacking them all on top of each other makes my fps a solid 20 lmao
