Sprite rendering stippled on Intel 965GM

[jspenguin]

I just downloaded the latest GZdoom SVN, and all sprites are rendered weird:



What could be causing this?

CPU: Intel(R) Pentium(R) Dual CPU T2330 @ 1.60GHz
GPU: Intel(R) 965GM 4.1.3002 (Mesa DRI)
OS: Kubuntu 8.04, kernel 2.6.24-19-generic x86_64

I know others have had problems with the 64-bit build, but this seems more like a GPU problem.

Edit: almost forgot, GZdoom version is v1.2.1 - SVN revision 321

Also, setting "gl_forcemultipass 1" seems to cause the same effect on flats.

Edit 2: Just compiled a 32-bit version, same problem.

I'm sorry but I can't do much here. Your driver obviously has serious problems - not that it surprises me with Intel.
