ghost images/trails of windows when moving

Hello,

I've encountered Ghosting on a Dell Vostro 3750 Laptop, Ubuntu 16.04, DisplayLink Driver 1.2.65 and Unity Desktop.

Especial Java based Applications like Eclipse and Qsys from Intel/Altera.
In Java based applications most of the time I saw only a grey background
Using VLC showed Ghosting when expanding the Video to Fullscreen. Watching Videos in their native resolution worked.

When using the internal graphics of the laptop every thing works fine.

To get me back working I switched from Unity to Gnome Flashback (Compiz). Gnome Flashback (Metacity) worked better than Untity desktop but not as fas as good as Compiz.
By the way: CPU consumption of the driver dropped from 30% (Unity) to 5% (Compiz).
