Noise in games on Intel HD Graphics 2000

Hi,

I'm running on Intel i3 2100 integrated graphics, I'm getting some strange noise particles in games like Minecraft and Speed Dreams (mostly noticeable in Minecraft) after playing a while, like half an hour. After that restarting game doesn't help, only computer restart have the effect of returning graphics to normal. Some screenshots bellow:

I'm running Fedora 16. On Fedora 15 I have experienced the same issue.

Best regards
