My Card Model : XFX R9 280x Double Dissipation (1000/1500)
I fought with this for a while and I've noticed a trend with forum postings on the issue, either people aren't really resolving it or they're not coming back to post what they did to resolve it!
I had the 2D flickering / jumping issue where the screen would jump downwards for just a split second while browsing or whatever. It was happening when the card would shift clock frequencies on the GPU & Mem, or at least that's what I identified as happening when the flicker / jump occurred.
I tried many different driver versions, 13.12 seemed like it had the least amount of jumping. At one point I had it set so my GPU was never sleeping, that prevented the jumps as well. Thinking I'd go down the BIOS route only after I had exhausted other possibilities, after all it's a new card and XFX doesn't post any BIOS downloads on their webpage...
So the other day I got sick and tired of it, and it actually was messing with my head (headaches) while I was working on some programming. Lines of text and that jumping every 30-60 seconds will drive you nuts and make your eyes sore, I had to get it fixed.
Over at this webpage you can search for BIOSes for your video card:

(That webpage is a search for my XFX card and model, you'll need to adjust it for your card)
Looking at the options there it was hard to tell which one to try, people said the Double Dissipation Black Edition was fine to use on the previous non-Black model and would provide a small speed boost. I tried about 4 different BIOSes before I found the one that worked best for me, the one at the top of the list compiled '2014-01-16 03:04:00'. Note that this is a Black edition firmware, but I only loaded it as the others either didn't fix the flicker, or weren't initialized properly within windows. (Low res mode, complaints the video card wasn't working)
I used ATIWinflash to flash the BIOSes and GPU-Z to backup my original BIOS and inspect the card's BIOS versions before & after flashing.
Not sure that this particular BIOS would fix it for people, so I thought I would list my troubleshooting list in hopes it leads someone to a fix.
It's an old thread I know, but this problem literally gave me a headache and I wanted to get my tests and results out there for people to see.
