There is a workaround with claimed success at the battle.net forums:
Quote from Lettus[1]:
I had the same problem last night running crossfired 4890s, but I fixed it. This is what I did.
1. DL Driver Sweeper
2. DL latest Drivers with CCC(don't install yet)
3. Run the driversetup so you can uninstall existing drivers via the CCC install/uninstall.
4. Restart computer into safe mode
5. Run Drive Sweeper and delete all ATI driver remnants only
6. Boot into normal mode and install new drivers and CCC then restart again
7. Profit

Most desktop graphics cards are nominally supposed to be able to run hotter than that, up to maybe something like 105 Celsius. As an idea, see the temperature graph here. Their HD 4850 reached 88 Celsius at full load and 86 Celsius while playing Crysis, and some other cards were hotter than that. That said, there's no harm in checking the GPU fan and heatsink for dust. Anyhow, streaky lights like you see are usually just symptoms of dying hardware, like people have been saying. Usually if you lower graphics settings, you will stress the card less. Symptoms may disappear this way, and you might extend the life of the card a little longer. If you want a real fix, you can buy a new GPU. So 87 is the top out range temp after playing some more which according to your graph is somewhat standard for my card so it's not overheating which shouldn't mean that it's artifacting. I'm at a loss as to how to fix this issue. It's clearly a problem with rendering the jetfire coming out of the scvs and other fire/explosion related graphics. Like I said, I had already updated the driver software and it's still an issue. Any other ideas? Do you think uninstall and reinstalling would make a difference at all? Thanks
I had similar graphics artifacts on a couple old cards from previous computers. It's exactly as everyone has said. Your card is, unfortunately, dying, and this is most likely due to heat damage. You said you checked the temperature after you'd already exited out of SC2, and after only playing one game...that's not going to give you a terribly accurate picture of how hot your card runs unless you normally only play one game of SC2 at a time. Additionally, that graph is only to give a very general rough idea before the fact. You would compare your card's temperatures to that graph only if you're curious about where its temperature should roughly be at. After symptoms have already manifested, there's no point - the fact of the matter is that your card is damaged. If your card wasn't running above expected temperatures, then it could mean you had a defective card or something of the sort. Regardless, the first step is to turn down your graphics as low as possible. After that, either deal with it or you'll have to buy a new card. It sucks, but shit happens :\

Clearly an off-screen colossus. All other images are from overuse of the /dance command, where clearly the background has started a disco theme to join in with the breakdancing units.
Good luck with your graphics card  Definitely the coolest bug I've seen though.

Thanks! This worked. It must have been old drivers still scattered around. As soon as I cleaned it everything works great.

I want this bug so bad... But as an option, so I can turn it on and off. =)

* A strange bug where SCVs were not rendering properly has been fixed. Now they shoot multicolored lasers.

I have played on low and medium while turning reflections off and the scvs are still shooting laser beams. Was considering uninstalling and reinstalling the game perhaps? It is possible that the card is getting fried as I use this computer to multitable Poker tournaments while running a poker tracking software in the background. All my other games run fine though as far as I can tell. Thanks. edit: I guess I should add that I run two 27 inch monitors as well...hmm...maybe it's time for a graphic card upgrade? It would just seem that it should handle it fine on lower settings.
hmmm odd that lower settings doesnt fix it, usually this sort of thing is because your trying to render too many polygons, but itd be a ton worse in ultra than low if that were it

Ok, posted the same thing in another thread before(about the same thing). Anyways, here's my case:
First it happened on my old PC - P4 3GHz, 2x512mb DDR-400, Sapphire 1950GT(AGP,512), FSP Bluestorm 2 350W. That was a few months (maybe a single one) after Crysis was released - dunno if I did something to provoke it (not that catalyst ain't capable of fucking itself up if it wants to) but the gfx got all corrupted. Same case as yours - Halo objects going nuts (i.e. those beams and stuff). I fixed it then by swapping drivers with the omega ATI drivers.
So, the last case - started around april or so this year I think. System - C2Q9400@2.66, 2x2GB DDR-2 1066RAM@800 due to mobo, p45 chipset(AsRock p45turbotwins200 DDR2/3 hybrid), Sapphire HD4870 512MB reference card, X-Fi Prelude. Symptoms - what you have, really - streched SCV/ambient(wind/stuff)/whatever particles in StarCraft, Risen completely unplayable (guess it uses halos for whatnot), same for Crysis. What was playable - RBR, X3 Terran Conflict, CS1.6 (i.e. goldsrc games), stuff like that. Rolled back to older drivers - no problems. Dunno the exact driver number, but after it any drivers messed it up. That on winXP SP3 32bit with official drivers. Thing is - I had to replace my PSU (FSP Everest 800W) several months later so that might have been the problem too, still the drivers were very specific in the way that after a certain release they all exhibited the particle streching (as for the PSU replacement - 1st it would not boot with a 5850 twin frozr 2 xcept on -cold- start, 2nd it'd shut down if the VGA drew more than 50amps on the VDDCs). As for windows 7 - no such problems so far. Hope this helps, gtg now (at school).
