Moving around mostly! I think there was one occasion where I wasn't moving the camera and it was flashing between blue and normal, but to be honest, I gave up building on that lot and started from scratch on another lot. The issue might still be around for some people or if I go back, but for this one I just gave up.
I think this may be an issue with your FX Card rather then the game. I just got a large update from NVIDA. Maybe look for updates for your card drivers and try again.
Oh great, yes I use NVIDIA too so will have a look for updates. Thank you!
