Well, 'proper' fix would be not changing the stream-size if I change the
transparency of video player, right?
I have backported this patch to rhel6 (spice 0.12.4 + patches) and it
seems much better solution than the proposal patch that I had mainly
because, now, does not really matter if the sized stream is correct or
not but jpeg would always use the correct parameters in the encoder.
I did not try this upstream yet but so far, patch looks good to me.

Btw, now spice-server on rhel6 looks good while virt-viewer crashed ;)
