Odd black pixels and messed up text

I installed a SAPPHIRE 100355-1GOCL Radeon HD 7850 three nights ago and for the past two days I've had an issue with these black pixels showing up randomly and at other times some text will distort for a few seconds then fix itself. The black pixels will go away when I scroll the browser window.

I did update the driver on day two which is the day this started. So could that be the cause here? I'm using an HDMI cable to a 32' Sony Bravia TV as my monitor.

What's really odd is I've played multiple games with no issues even using high to very high settings, just minor hiccups here and there, but none of these black pixels or text issues. So far those seem to only happen when using my browser which is Firefox 19.0.2. I use the Goggle Chrome browser a good bit too and haven't had the issue there.

What I'm really worried about is there being an issue with the card as I'll only have a short time to RMA it if that is the case.

Here is an image of it happening here while I was reading a thread on this forum.

I rolled back the driver and they seemed to have stopped showing up. So I've tried re-downloading the newest driver again and I got them again. So now I'm confused as to what I should do. I even tested AMD's newest beta driver and had the same issue.
