I tested with one environment where I have two VMs under oVirt 4.2 and I
connect to them using remote-viewer and spice in full screen mode.
One is a fully updated CentOS 7 VM
One is a (not fully up to date) Fedora 28 VM
Both using Mate as DE. On CentOS 7 Mate 1.16.2. On F28 1.20.1
I confirm on both the setting is true and I never tricked with it, so it
should be the default.
Below is a PyQT4 python script that shows the issues:

I confirm exactly your behaviour with CentOS 7. The toggle makes the drop
down to remain expanded and if I move the window the drop down remains
where it was.
With F28 all is ok and as expected

I confirm no transaprent background on both and correct behaviour on both

Anyone have any idea what the problem(s) might be and how to fix it/them ?
