Well, I get the below. ex_expose has this for some reason:

al_set_new_display_format(ALLEGRO_PIXEL_FORMAT_ANY_32_NO_ALPHA);

If that is wrong, what should it be instead?
ALLEGRO_PIXEL_FORMAT_ANY_NO_ALPHA? ALLEGRO_PIXEL_FORMAT_ANY_32?
ALLEGRO_PIXEL_FORMAT_ANY_24? Or should I just remove the call
completely?

I guess it would be better to have a requested format only fail if
absolutely necessary. In this case, all the 24 bit formats with alpha 0
are what the user intended - they are RGBX after all, just GLX doesn't
report that "X" separately as bits.

24 bit and 0 alpha is not RGBX, that's RGB. ALLEGRO_PIXEL_FORMAT_ANY_NO_ALPHA covers both. I don't know why ex_expose had that call.
