Description: The screen (especially terminal programs such as Terminal and Terminator) do not refresh properly when using any kind of remote desktop. There is occasionally quite a long lag, for example, when typing into a terminal window. If I switch to nouveau driver the issue goes away completely. The issue appears with both nVidia 430 and 440 versions. Old drivers don't support RTX 20 cards so I can't for example try 390.
I tried different remote desktop servers such as the NX NoMachine, and VNC vine, as well as different clients on MacOS and Windows, I even tried TeamViewer, all behave the same.
I have reinstalled Ubuntu 18.04 and no change.
Both the server and client are connected to wired gigabit router.
The issue is there since like two years. Not addressed by nVidia.
I see it with Ubuntu 18.04 and GeForce GTX 750 Ti, using X11VNC to connect.
Enabling seconds in GNOME clock makes the screen refresh at least once a second, which helps if you need a fast workaround:
