Slow user interface with vnc, TeamViewer, Anydesk

(1/2) > >>

Gedeon:
My Linux MC is a headless machine. With remote desktop tools I can manage most graphic interface apps with  really good response an low latency. However JRiver UI is too slow.

¿ Any way to optimize/improve that behaviour ?

Thanks.

I too ran into the slowness over remote X11, and found this QTBUG-50338. There is a link to their tracking to fix the issue at the end of the thread.

Gedeon:
Thanks for the insight. But I Guess those bugs are solved in latest qt versions.

You are welcome.

Though it does not seem that it is solved. As this comment notes, the fundamental issues are still there - and it refers back to the comment I linked above. A few commenters since confirmed continued slowness.

Gedeon:
Sadly, I've been testing UI with a real display attached, and the UI is also sluggish. Just a bit better than remote, not too much better really.

In my setup (J3455 + 8gb RAM + SSD / Lubuntu 20.04) the response time is miles away from my Windows machines (some are older than this one)

I hope one day some kind of Qt Linux optimization could be applied to the linking/compilation process.


Edit: Just wanted to add that I found an option: raster VS native in a Qt forum. It's old but It seems It solved some performance issues for Apollo Lake.  But I'm not by any means a Qt programmer or a UI expert.
