I don't know if this problem is only presented to me, but I find that if you leave your mouse cursor in the bottom left of yoru screen (over health, mana, or energy) then a random item card from your equipment shows up. if left their during your character passing a load zone it gets stuck on the screen till another load zone is passed through.
This of course is annoying if in big areas and is chaining quests, yes one could argue to just mark your spot, warp home, and go back to remove it but if you do all of that and leave your cursor in the corner again its a waste of time and a break from your flow.
if in need of screenshots I took 2 (Screenshots removed per the rules. ~Dworgyn)
Fixing this would be appreciated because out of habbit and years of playing this I leave my cursor close to my health
