I got this too. I think it's fixed by
a46d3b338ed362e6dfad359db3d9a505bff0dc9c upstream. This is bad enough -
it completely breaks screen sharing for me - that I think fixing in
update/SRU rather than waiting for a point release would be warranted,
will upload it.
I'll write my testcase in the description in a minute. Alex, if you
could add your one too, that would be good for the SRU! Also if you
could check if the package fixes it for you (it does for me).
