UI bug with minions

I'm leveling a witch and getting this bug where all the minion icons at the top left are stacking on top of each other. I'm not sure, but I think it might be something to do with either shapeshifting, because I'm weapon swapping to a wolf to get pounce minions, or perhaps because I'm weapon-swapping with a scepter, so the amount of minions I have keeps changing. This is a bit annoying since I'm trying to focus on temporary minions and I'd like to keep track of how many I have up.

Okay, just tested a bit more, and it seems like this is caused by the pounce skill.
