--- Comment #5 from Rico kgbricola@web.de 2012-08-20 05:20:37 CDT --- The game looks fine here and the bodies could be seen with a C2Q and a radeon (2.1 Mesa 8.0.3, Gallium 0.4 on AMD RV710). I also tried taskset to 1 and kernel parameter maxcpus=1, both without success in replicating the issue.
I get the feeling, that the combination of the cpu / gpu (driver) makes the trouble. It would be nice, if we could check if the problem happens with combinations like (Athlon 64 and (radeon, intel gma or gforce>8000)) or (Intel cpu and geforce 7xxx). You also may give nouveau a try, but I'm not sure it will run the game at all.
If it is a regression, the regression test will show the faulty commit and will show a lot faster where the problem might come from. I don't expect much more trouble for the regression test, because you use a 32bit system (even if the cpu is capable of running 64bit, it runs in 32bit mode). Trouble may happen if you use a 64bit system. Though compiling wine on a single core cpu may take a while.
@Hardy Schumacher Could you try to limit the max number of cpus to 1 and see if the problem shows up again?
