Does the problem happen on videocards from different vendors?
Sure, like I said I can confirm it with the Intel i945 graphics chipset on the campus computer system (I don't know the driver version though). Then I can confirm it on a NV35 series nvidia card (the Geforce 5900 I mentioned before). I find out the driver version of the NV35 this evening. But I really doubt it's a hardware/driver problem (as it's not only happening with nv hardware).
At least due to the pixel format change there are now dozens of pixel formats to choose from. If the issue appears only on a certain driver then it is most likely a driver bug (e.g. the driver not liking the specific format). It could also be a bug in our opengl32 code where we might not return the correct info for a certain pixel format. Even then the issue might only appear on certain drivers because due to the way each driver orders the pixel format list, the game might have received a different format.
I have currently hard-masked a recent nv driver for my NV35 (169.xx ??? series). I could however remove the mask and test SS with this driver. Anything more I can do?
