Bug#929245: Caja screen glitches in multihead setups



At first glance it appears not as that issue is related to a highly obscure remote desktop setup my issue is local on xorg and its not merely failing to redraw on adding my two ext displays its not drawing desktop at all in this spot and is keeping any window that is drawn there after the window is destroyed. I will try the icon test mentioned in comments and see about giving some visuals.. can i send screenshots or videos or should i just link to them on my server?

Can you please confirm that this is a variant of upstream bug #945 [1]?
