valgrind doesn't understand some (not very) recent AMD specific instructions yet. I build everything with -march=amdfam10 -mtune=native to avoid this.
Ok, I'll recompile wine and try again.
Right, but video memory leaks are usually accompanied by corresponding system memory leaks, which can be caught by valgrind.
True, the game does noticeably leak system memory (1.5+ GiB footprint with precompiled shaders vs 500 MB with mono)
