That has also happened in Lost Coast and Sin: Emergence and it occurs when the mouse is moved, no other games have exhibited that corruption so I'm guessing it's a Source related issue, or a driver/Source issue. I'm running Nvidia Forceware 185.85 on Vista x64 with a brand new GTX260+. I'll update the drivers and see if it goes away. Anyone else had similar issues with the 185.85 drivers in Source games?
Edit: Damn! 185.85 are the latest drivers
