Some textures are not rendering correctly in apitrace

Hi José,
I have done quite intense testing of this evening, but I finally saw
something quite odd. So before sharing anything I need to be sure that I'm
not capturing the trace wrongly.
First of all, Serious Sam 3 is a Steam game. It's a 32-bit game. I'm on a
64-bit machine.
Here is how I build apitrace :
$ git clone https://github.com/apitrace/apitrace.git
$ cd apitrace
$ cmake -H. -Bbuild -DCMAKE_BUILD_TYPE=RelWithDebInfo -DENABLE_GUI=TRUE
$ make -C build
$ cmake \
-DCMAKE_C_FLAGS=-m32 \
-DCMAKE_CXX_FLAGS=-m32 \
-DCMAKE_EXE_LINKER_FLAGS=-m32 \
-DCMAKE_SYSTEM_LIBRARY_PATH=/usr/lib \
-DENABLE_GUI=FALSE \
-H. -Bbuild32
$ make -C build32 glxtrace
So I should now have a working apitrace in /home/benjamin/apitrace
I launch steam :
$ steam
Running Steam on fedora 19 64-bit

And in order to catch a trace of the game, I have modified the SS3
executable. The executable is located in
"/home/benjamin/.local/share/Steam/SteamApps/common/Serious Sam 3/Bin" and
is named "Sam3"
$ file "/home/benjamin/.local/share/Steam/SteamApps/common/Serious Sam
3/Bin/Sam3" gives :
ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically
linked (uses shared libs), for GNU/Linux 2.6.15,
BuildID[sha1]=0xaedfd266c84ecec32e8ff6e69f3f1eb8a5f78d46, stripped
So I moved the genuine exec :
$ mv Sam3 Sam3.old
And created a new "Sam3" shell script which is just :
#!/bin/sh
TRACE_FILE=/home/benjamin/testmesa/ss3_tmp.trace
LD_PRELOAD=/home/benjamin/apitrace/build32/wrappers/glxtrace.so
/home/benjamin/apitrace/build/apitrace trace --api gl ./Sam3.old
So now I just launch SS3 within Steam and here is the log (that I didn't
saw before) :

I suspect something is wrong in the manner I'm capturing the trace.
