Sorry if this has been discussed already.

I bought a Gigabyte Radeon 7950 Windforce around a month ago. It performs much as I would expect and runs games without any artifacts or stuttering problems.

I have noticed that when viewing certain websites the screen will flicker momentarily. I find this a little bit distracting - not massively so, but I would prefer if it didn't happen. I believe it happens on websites with videos or flash advertising primarily and it probably has something to do with the card ramping up the clock speeds and whatnot from its idle 2D mode.

Has anybody else with a similar card observed this and is there a way to stop this happening?
 
I also have a 7950 and this happens to regularly. Sometimes a few times a minute or once a day. Quite annoying I know. No problems in games when overclocked ect.

I'm looking for a solution now. Let me know if you find any solution. I'll post here if I find any myself
 
I had two 7970 Lightnings with the exact same problem. One of them seemed to get worse over time. I returned them both.
 
Seems to be a glut of this at the moment. Can you all replicate the steps you did to make it happen, what browser you're using etc? I can only replicate this issue when i use a faulty card whats going back for rma. But not everyones card can be faulty so...

No problems with my 7950. Have you tried disable hardware acceleration in flash to see if it helps?

Good shout, worth a try.

Are any of you using afterburners unofficial overclocking method or anything like that? That used to be the No1 cause of flickering when gpu clock speeds change.
 
No unofficial AB method here. Flash hardware accel makes no difference, especially since it still doesn't even work in Windows 8 yet. The largest instigator seems to be sites with pictures.

This has been a common problem for lots of people since Cat 12.4 to my knowledge (that's the earliest driver I tested, and I've also been updating drivers almost with every release). Driver or hardware issue, it could be either, and it's not likely someone has a concrete answer. Even though it's been around for so long it might get fixed at some point, though it's not worth holding your breath because not only do such problems sometimes take a while to be fixed, but obviously nothing can be done if it's a hardware design flaw. Best to ignore it for now (which is what I do).

Can you tell me how to replicate it ? I experienced an issue similar to this on my faulty 7950 but it never happens on the other one.
 
Aaaa. I could have linked you absolutely any forum page with pictures in the past as it used to happen much more commonly, but it happens much more rarely these days. I do think it's something to do with 3D clocks kicking in. The problem still only surfaces on sites with pictures. I'm trying to find a page that does it but I can't at the moment, so I'll try and post back when next it happens. It looks like a sort of 50px wide horizontal bar across the middle of the screen, and variations of it were happening on both my previous 7970s as well.

Furry muff.

Its weird it stopped happening to me as soon as i ditched Firefox and started using the official overclock method as outlined in my amd afterburner thread.
 
Yeah I'm using the official method, along with Chrome... and like I said it's really rare these days. I think it might actually be because the newer drivers kick up into 3D clocks much less often than before, though the problem is obviously still there. Having said that I haven't noticed the issue in 13.6s, but that's probably because I haven't had them long.

Keep us updated. :)
 
Rofl, took a good week and a half but hey hey, happened while scrolling down this site:

http://www.eventhubs.com/news/2013/jun/19/reports-microsoft-removing-xbox-one-drm/

Oddly enough the flicker didn't coincide with a clock change.

Actually as of January or so the random switch from 2D to 3D clocks (which happens very very rarely too) now coincides with a momentary black flash. The entire screen goes black for an entire second while the clocks spike to 3D clocks. No idea why it happens...

Tried it several times, didn't happen to me. Are you using afterburner and have you tried disabling ULPS?
 
It used to be a lot more predictable. I actually just went on the site now and I can't even reproduce it. It just seems to happen randomly once a fortnight or something, so not the big issue it used to be tbh.
 
i get it with my 7950 wf3, when i installed it i also upgraded to IE 10 which has quite a good adblock.. i thought it might have been from adverts trying to appear and immediately getting closed down
