What is this here ? Just ignoring me ?

@jobro: Not ignoring, just snowed under other things - sorry. In KDE you might want to change the compositor to something simpler, like xrender, or force full screen repaints. If you are willing to help us diagnose this more, it would be great if you could stop DisplayLink Service, and try other libevdi client to check if it also reproduces - e.g. monitorsim from https://github.com/mlukaszek/evdipp

Thanks,
Michal

Hi Michal,
thanks for your reply.
- xrender doesn't help
- force full screen repaints helps to get it working with two screens but disabled notebook screen. I haven't tried your approach with a alternative libevedi client, because I'm not familiar with this topic. Can you give me a more detailed explanation ?

Has anyone else notice that the trails are very pronounced when watching a video in VLC? Nearly unusable.

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).
