Interesting. Would you be able to provide logs so we have a chance to replicate here?

Cheers,

This tool would capture what we normally find useful.

@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 ?
