Running with core-image-weston, on the other hand, I hit another case:

WARNING **: GDK is not able to create a GL context, falling back to glReadPixels (slow!): Unable to create a GL context.

Then the animation runs, but pretty slowly, to the point that with WEBKIT_DISABLE_COMPOSITING_MODE=1 it is faster.

Running with Mesa VC4 as well.
