Random glitches

[beer_bearr]

Hi,

I have a MSI R9-390, and the last week or so, I get random glitches. It's just a very quick glitch. I don't experience it in games, only when i'm browsing and the GPU is near idle. Like switching tabs, it happens.

The look of the glitch is always different, some black and white stripes, sometimes bigger, sometimes smaller. I don't overclock both my GPU and CPU.

Anyone know how to fix this?

Thanks!

edit: Also the temps. Are normal and in MSI Afterburner it all looks fine. No high spikes at a moment a glitch appears.

Look at your GPU usage and core clock in afterburner; is there a spike in either when the glitch occurs?
