I am experiencing the same thing. It’s really bad on something like the “Runelocked Chest” WQ in Nazjatar, the match three one. My cursor gets stuck continually within the runes, like there’s some kind of barrier not allowing it to move out of the rune. Super weird.
I have had it happen all kinds of other places, too. When mousing over an NPC, when mousing over a treasure chest in Mechagon, when mousing over random enemies. I’ll note that I’ve never experienced this “sticky cursor” thing when in an addon window or browsing options.
This happens regardless of how the cvar rawmouseinput is set. Tried on and off.
Me too, two different corded mice (a logitech, and a razer) and a wireless logitech. All three do the exact same thing.
