Losing tooltip focus using controller: ghost mouse inputs

I’m using a controller on PC and when hovering over an item the tooltip stays visible for like 2 seconds then fades away. Like wtf. I have to constantly move off and on the item to keep the tooltip visible. The same behavior happens on the skilltree. This doesn’t happen using the mouse cursor…it stays visible so long as you are mousing over the item/skill.

edit
After further investigation I don’t think it’s fading too fast but rather it seems to keep getting ghost mouse inputs as if I’m moving the mouse which “moves” the cursor off whatever I’m hovering over. This happens after like 3-5 seconds no matter what I do. Even if I set the controller down and don’t touch anything the mouse cursor just randomly appears on the screen and the focus moves to whatever is under it. Really annoying.

Does anyone know of a fix/workaround for this silly behavior? I couldn’t find anything in the options but maybe I’m missing it.
