Starting today when using firefox browser my cursor has started to flicker between the pointer and the hand erratically. There is also a delay when trying to type anything in a text box, search bar or browser address bar which is making it hard to operate. I have refreshed, restarted and also reinstalled firefox a fresh and still no luck. It's specific to my wacom pen that i use. I have been using firefox for decades and don't want to change to another browser - but if i cant solve this I might have to.

I also reinstalled wacom drivers, disabled the hardware performance setting in firefox, cleared cache, updated any of my windows drivers that needed it. And now am at a loss. any ideas?
