I don't understand the first shot at all. What should it look like?

In that second picture, it looks like you're having some z-fighting
issues with that wall on the left. Do you have, say, the wall made out
of a brush entity, and have a skybox brush overlapping it?

Or are you doing anything strange with a 3D skbox and a sky_camera? Try
disabling them, if so, and see if you get the same issues.

Edit: And what's that texture I can see in the sky in the Hammer shot? (Playerclip?)

Check your compile log, is there ****leaked**** in it? If so FIX THE LEAK!
