use-damage=0 turns off ximagesrc using the X Damage extension. That
extension tells an application (ximagesrc in this case) what parts of
a screen have changed, so its possible to send out small updates
rather than sending whole screens.

For some reason, ximagesrc doesn't behave right when using Damage. I
think its sending out partial-screens without any indication in the
buffer/caps that that is what it is doing, and so the pipeline gets
confused.  At least, that's my best guess.
