Yes, the whole point of --use-pixman is to use Pixman software rendering wh=
ich
will be faster than GL with a software renderer. If anything, it will disab=
le
hardware acceleration for the compositor and apps.

It is used to get something on screen, when hardware acceleration doesn't w=
ork
for any reason.

Daniel's guess in comment #3 is=
 still the best guess here.

One thing to test to confirm would be to hack Weston's build so that
HAVE_GBM_MODIFIERS will not get defined. If that works, then we know that u=
sing
gbm_surface_create_with_modifiers() does not work while gbm_surface_create()
works.
