I’m having this issue as well. I can recreate the issue 100%. It seems to occur when I mouse over an offhand or one handed weapon.
It seems to happen if I have a 2handed stave equipped, in particular an awakened Kharnalex that’s fully upgraded, it doesn’t crash me if I unequip the item and mouse over other items.
This is the oddest thing.
No addons, updated video card drivers, wtf folder deleted and it still happens.
