With a few videos on a page, GtkLauncher seemed less responsive with accelerated compositing than without. So unless, there is a better way to achieve that, it seems like it decreases performance. I do not have numbers to back that claim though.

Could it be that you are uploading and downloading  to th GPU more than you think? What happens if you turn the shader off and just render the YUV data directly? Is accelerated compositing slow for you, in general?
