Can you capture a trace using https://github.com/apitrace/apitrace your distribution might have package for it. Also try to make the trace as small as possible by jumping directly to the issue.
Well I got one but it's 186 meg compressed.
That's as small as I can get it - made a demo where you can see the issue and then loaded it directly from command line +exec a_script thus bypassing the 3D menu screen and made the game quit after rendering just 5 frames (1 isn't any better).
I guess the screen while the map is (slowly) loading is accounting for a lot of the data.
Do you have somewhere I can upload 186 meg?
