When using multiple d3dvideosink elements in the same pipeline the frame rate
drops very noticeably for some of the video sinks.

Here is my pipeline:
uridecodebin name=vehiclebin uri=rtsp://127.0.0.1:8554/vehicle.sdp !
tee name=tp
tp. ! queue ! videocrop top=0   left=10  right=376 bottom=290 ! d3dvideosink
name=rear
tp. ! queue ! videocrop top=0   left=400 right=0   bottom=290 ! d3dvideosink
name=forward
tp. ! queue ! videocrop top=290 left=10  right=376 bottom=6   ! d3dvideosink
name=left
tp. ! queue ! videocrop top=290 left=398 right=0   bottom=6   ! d3dvideosink
name=right

The video plays smoothly with 1.0.10 but will not play at all with versions up
to 1.3.91 due to a different bug.
