Some textures are not rendering correctly in apitrace

I tried to follow the procedure in the link you pointed, but I couldn't
make it works. So I just disabled the Steam Overlay as said, and continued
to catch the trace with my modified "Sam3" file, which should works after
all.

Just disabling the overlay doesn't solve the glitches.
So I tested your 3 patches, unfortunately none of them has improved the
situation : as usual, sometimes there is no glitches at all but most of
times glitches appears while retracing.

If you need them, here are some of the traces :
- trace with zlib patch, the glitches are a bit different than usual :

(174 MB) md5sum 1b109d36e7760968ad8ce04bc4d22fe9
- trace with glfinish patch :

- again a trace with glfinish patch, glitches are different from the first
one :

Tomorrow, I will test with a GeForce GT210 (nouveau).
