valgrind output
sadly there comes nothing more, because valgrind seems to be inside a 100% cpu
loop. I will try to get a better output with a non-steam version (I got the
game from humblebundle, so this is easy)

I am using Gentoo/Linux, but valgrind for some reasons didn't want to read my
external debug files, so I had to rebuild the libraries without stripping the
binaries, which obviously worked.
I will upload a new valgrind output file after I get the new game files and can
try again. As it seems the issue inside mesa could be false alarms or not
important at all.</pre>
