Confirming with sample presentation attachment 135677, The pixel artifacts are
present with Hardware Acceleration, absent with OpenGL and CPU only rendering,
that text rendering issue is bug 107090

Weird, as handling of the transparency of the Text box animation is correct
with HA, but goes opaque with CPU only or with OpenGL rendering. That is--as
animation begin (entrance split, or exit split) the transparent text box goes
opaque and is then animated. But it is correct with Hardware Acceleration.
