My mouse pointer vanishes when I’m running maelstrom & summon 5 thorn totems and using swipe with almost 200% increased melee attach speed. It usually takes 2 or 3 seconds for the mouse pointer to return.
At first I thought it was just a lot going on and I couldn’t see the pointer, but now I’m able to reproduce it with just 2 enemies on the screen. When this happens I’m also seeing a huge drop in fps. Seems like more of an issue the first time thorn totems drop in the area.
