Vapor-X r9 290 Artifacts when idle

[killingdyl]

So ive had my Sapphire R9 290 Vapor-X for about 2 months now and i have noticed that when my computer is idle or when i am just surfing the internet artifacts, lines, flicker randomly on my monitor. However the weird thing is the minute any kind of graphicly intense operation takes place such as a video play back on youtube, mpc, or playing a game the artifacts disappear and stay disappeared until about an hour after the graphic's card cooled down. My card came factory overclocked, but i dont think that should be a problem since this only happens when the card is idle and the clock speed is ramped down.

Edit: forgot to mention that even when the video or game is in the background or in another tab gets rid of the artifacts

if your not familiar artifact show up cause of hardware failure.i recommend recheck power cables ,if that didnt help then return for waranty

But i find it odd that when the graphics card starts to do work by rendering a video that the artifacts disappear completely until a while after it has finished working and starts idling again.

It is a driver problem. This was known for many 290s / 290Xs out there. Are you using the latest driver?
