The game doesn't create a window and hangs with 100% cpu usage right after
starting. There is nothing relevant in the terminal output.
Doesn't happen when UseEGL=Y.

Caused by
commit 0b7e785da4f45a8da6a977db9b05c729132f8afa

Can be reproduced with the non-Steam demo as well (installer needs mfc42.dll)

Thanks, though I'm unable to reproduce the issue on AMD sadly. I'm tempted to
change the default to use EGL... seems like a good excuse, but I don't know if
it's a good idea :)

Yes please, go ahead with that :)
For me, the best argument in favor of using EGL was that bug #58064 has been
reintroduced shortly after it was fixed in 10.10 when using the GLX backend and
that affects quite a few games. That problem doesn't occur with the EGL
backend.

Marking fixed as EGL is the default backend now in 10.17 and the problem is not
reproducible with that.

...bad argument, if I ever seen one.

The bug is likely still there in the other backend, so until that codepath gets
trimmed, instead of just made non-default, the bug remains valid, if no longer
a priority.
