Just bought a Sapphire R7 250x 1GB GDDR5 and have the following 2 issues;

First, and rather easy to explain, is 2 inch horizontal green/black lines appearing during certain video playback i.e can go to youtube and watch 10 videos and about half will be unwatchable due to the lines. See Screenshot.

Secondly, and more confusingly is the way fonts are getting rendered but only in certain places by certain programs. I'll elaborate, I can browse the net using chrome without any issues but if I was to try using IE, the fonts will be rendered with lines through them. See Screenshot. This happens in other programs too.

All drivers are up to date, off a fresh install, VGA cable is fine & tested, Monitor is fine and tested. Had the card less than a week so will return If no one has a solution but thanks in advance for your replies!!

OS:Win 7 Ultimate 64 Bit.
