[Bug 38178] Crash with Heroes VI at very begin

https://bugs.winehq.org/show_bug.cgi?id=38178

--- Comment #29 from Stefan Dösinger  ---
If I remember correctly the crash occurred outside of Wine's code because the
update_volume call corrupts memory. A backtrace should give some clues though.

I have patches that fix this properly, by keeping track of format capabilities
for each GL resource type separately. I will send them in the next days. Right
now I'm busy with some more regressions caused by my focus loss handling
patches.
