Comment # 7 on bug 44647 from Nicolai H�hnle

This is an application bug (though I don't know whether the fault lies with
Wine or with CoD4): there is insufficient synchronization between different
contexts.

If you look e.g. at Frame 5, there is a sequence of glTexSubImage2D calls for
textures 64 to 66 running in context 3.

The command sequence switches to context 2 in call 75827, and the textures are
used in call 76024, still on context 2 and without any flush or fence command
in between to ensure that the TexSubImage commands are actually executed.
