I've been trying to find help for a problem that a couple of my players are
having, and I figured someone here might be able to help.

I have one mac player using a Mac G4 and one using a G5. On some of my maps
(most are modded), they run into problems where they see blue or orange on
their whole screen, except for their HUD. I was just online with one of them
on Stadt, which I just modded (spawned some items) and he is now
experiencing it on that map. From a quick check, it appears that it may be
happening only when the sky is visible, as he was able to see fine in the
church, then when he got outside, it went blue. Same with when he was in the
tower and when he reached the junction in the sewer, where the sky is
visible... he could see just fine in the tunnel until then.

Is this a problem anyone has heard of before?
