Thanks for the prompt response. What would be the solution to that, then?

Hmm, it may indeed be the driver/kernel (that KMS, UXA and DRI2
thing). Google showed some results from the Phoronix forums, and those
who complained of this specific issue were not all on an Intel GPU.
Some have stuff like R4550:

And when I ran with LIBGL_ALWAYS_INDIRECT=1 it exhibited playable
framerates (could be smoother, but it may just be the Intel GMA
itself). I was enjoying the first few minutes of the game until I
think when I reached the end of "Part 1" or the "tutorial" (after
singing). Then it crashed. Attached is the full CLI output.

Something may be terribly wrong with upstream graphics codebase
(intel, ati, mesa). I mean it's not always we have native releases, so
there might be some kind of missing code for this one (which the game
makes use of). I initially thought it was intel's new UXA renderer
(since the game is 2D), but now I think it's GL's 2D extensions that
need a look.

The game is a fantastic piece of art. The sound, the graphics, the
music, genius. But this is the kind of thing that might delay a
non-beta release or even eliminate it.
