After days of testing we managed to get the default Nb8.2 install to behave in the same flickering way after removing this JVM argument from netbeans,conf. I can only conclude this argument is a MUST TO HAVE even though I have no idea what it really is doing, adding it to my RCP's conf file did solve the problem.
