6870 Screen flicker problem :/

[Vinnydude]

Over the past few days I've been getting the occasional screen glitches. Its happened maybe three times now and it starts from boot, firefox seems to make it flicker more, and scrolling in firefox makes it considerably worse. It's not just in firefox though, it just makes it worse!

It's not an intermittent cable as I've checked them all. The flicker is odd too, it's a copy of what's on screen, but positioned halfway down the page and then slightly off centre.

I'm pretty sure this didn't happen before I updated to 12.6, i'm wondering if anyone else has had this since the update?

Oh, and so far, a restart has sorted it out!

Very odd indeed.

Any help is more than welcome

As the problem was happening straight from boot, I didn't try it in a game, so it could possibly be that. Strange how it's only just started doing it though.

I shall give this a try next time it happens and see if it makes a difference.

Any more suggestions are more than welome

Where am I looking for the 2d/3d clock values? I can only pull up the standard overclock stuff (which is set to default)

I'm still getting this issue, I had upgraded my drivers to the new beta ones and had thought I'd got it solved untill a few minutes ago when I booted up and it happened again. Just turned off ATI overdrive, won't know if thats worked untill a good few restarts as its not every boot that it happens.

The way the flicker behaves almost feels like its tied in with either hard drive access or network access. It is always straight form boot though and opening firefox makes it worse!
