I don't see that, but I do see X jumping around between 20-50% cpu
which is more than I'd expect.
What theme are you testing with?

There are two changes, I'd like you to try if you don't mind.

1) get rid of the cairo_push_group () / cairo_pop_group_to_source ();
cairo_paint () calls.
Those calls just add an extra copy that we don't really need, and are
probably the root of your problem

2) change gdk_display_flush()  to gdk_display_sync ().  This will
throttle plymouth draw requests if the X server is having trouble
keeping up.

Do either or both of those changes fix your issue?
