possible, I will give it a try and add there a debug statement.

ok, that'll work for the effects (always translucent - easy enough, they don't 
exist in non compositing) and should work for tabbox by setting a context 
property.

But won't work for the script which uses PlasmaCore.Dialog. If it's really a 
problem with KWindowSystem and KWin, we can think of a solution for 4.11 
(hidden property or something like that).
