Two graphics issues

Linux Mint 12. Intel Mesa integrated graphics. Drivers updated (incidentally, which all packages are graphics driver-related? I've been doing it rather blindly so far.)

1. Strange specks in rendering
2. Whenever I see the Strike Commander (mine or anyone else's) -
It usually has some parts missing
It walks like it's limping
The units and buildings around it fly around where they are NOT supposed to be, I only see shadows and/or ground decals, so I have to play in icon mode.

Thanks.

Thank you, GoogleFrog, but I can't get the first to happen again. =\ (It's pretty random, some times it's there sometimes it isn't. I forgot to mention that it happens in other 3D games as well.)

What could I do for the second?
