when using unity2D it uses metacity with compositing enabled and that has
an impact on the GPU load. since we rely on GPU for video rendering
(pvrvideosink) that has an impact on the rendering. disabling compositing
really help here (using gnome fallback for example).

we have some updates (not published yet) with some bug fixes in
pvrvideosink (fixing some jerkyness) and improving the quality of the
rendering.
