I'm bumping this as well. I am also submitting a ticket.
I just noticed it with some of the latest patching in the beginning of march. Now I'm not on any fancy hardware, a MBA with nvidia 320m. I have basically the lowest graphic settings possible and it is still happening to me.
It sometimes looks like a flickering of some parts. Like in system the halo around the planet will flicker on and off. and on planet the sky background will do the same things. And finally in infected I noticed a square around the queen that eventually turned into her plasma trail.
This defidently isn't the answer for everyone, but has anyone tried switching from an ATi card to an nVidia one? mabey even just borrowing it from a friends computer for a day and seeing if you still have that problem?
I just noticed ALOT of people with this problem have mentioned ATi video cards.
I've just started having this problem. It worked fine two days ago and now it's doing this. Only does it after I log into my character. I even tried creating a new character and it does it on that too. I can open other windows in the game, just the game itself is flickering.
I've only had this problem since the season 4 update. So to me it's a software issue. Running an ATI mobility radeon 5145 HD in a sony vaio with a triple core amd phenom 1.9 GHz and 6gb of ram, windows 7 64-bit.
