Oh, I never tested Karol's patches and didn't entirely understand them, to be
honest. I don't think those patches actually tried to fix the ApplyConstants
crash, just the lack of ARB_shading_language_include. Would you try my patch
instead? It's merged to Mesa git master now (thanks Timothy!), so you can just
build stock Mesa.

I've just re-tested that Mesa commit cf6dadb00b93b828e8cc95e8136d4c2013d76e40,
which was the newest when I checked a few minutes ago, works with this game for
me on Intel graphics.

I'm using two workarounds in addition to the Mesa fix. One is
MESA_GL_VERSION_OVERRIDE=4.2. The other is to configure the game to cap its
frame-rate to 15 fps, because if the game renders frames too quickly, I get all
sorts of wrong drawing. (Sarah glanced at it and thought it might be missing
sync fences or some such thing, leading to some rendering finishing after the
buffer swap.)

Even then I have some textures getting sprayed on the screen in places they
shouldn't be and UI icons often failing to show up at all, but the game is
fairly playable for me.

If you still get the ApplyConstants crash with the git master version of Mesa,
I'm afraid you're going to have to do more debugging to find out why, since I
can't reproduce the problem any more.
