The first problem is that every now and then my adrenal skills will not light up. They just seem to get stuck at dark. I can still use them, but I have to spam to see if they are charged up. This has happened several times. Mostly in Crystal Desert and Ettins back.
The second is that some monsters' health bars come up empty like they are already dead. This seems to happen more in Ettins Back and the Undead rangers in Kryta.
Two GUI problems
Arton
Sir Skullcrasher
oh your second problem, i seen that alot! i think its not a videocard problem but a glitch within the game that show certain monster to have zero health when they in fact has full health!
Synxernal
I get those problems as well.
