Monster indicator glitched

as the title says my monster range indicator on the attacks in bugged, happens aswell with all attacks that have a radius or charge timer i get the actual ring and mirrored/along side the entire screen is ghost range indicators which was fine at first but when i got to the Sunken Temple of Quarn all i see if a blue floor and not sure which indicator is the real thing and the other false,
for those unsure of what i mean here is an image : http://i.imgur.com/5hjjF40.jpg
any idea why this is happening? :<

also my drivers are all up to date

i sent a ticket about this and they basically said sorry bro but post it here.
