Apitrace warnings

The game "War Thunder" doesn't seem to be working with Mesa.

I get a green screen instead of what I'm guessing is an intro video, and a
black screen in the menu. Happens on i965 and with software rendering, reported
to be the same on radeon.

Same behavior on 10.6.7 and 11.0.2. 

The game is free to play:

I created an apitrace, that results in a lot of logged warnings:
