Screen tearing and slow screen updates with Win10 to Win11 connection

[lukyduck]

I have a connection problem between 2 Windows machines. In the past, this exact connection has worked fine and I have spent hours doing remote designs using Fusion360, as well as using other applications. Suddenly, the connection is very poor. I have updated NoMachine, so I am running the same version on both ends.

My Network – Local, I have a Windows 10 PRO Desktop and a Linux Ubuntu laptop. At the remote end, I have a Windows 11 desktop PC and a Linux desktop PC. Both Windows PCs are running the latest NoMachine version 9.6.3

When I connect to the remote Win11 PC from my local Win10 PC, the video is poor, screen tearing, very slow updates, and I can not even perform basic functions using my mouse. It is unusable

BUT – If I connect to a Linux PC (Ubuntu) at the remote location (same network as the Win11 PC), and THEN connect to the Win11 box through the remote Linux box, the connection is much better. So, it seems that I have this issue only when connecting to the remote Win11 PC directly from the local Win10 PC.

Any suggestions on where to look would be much appreciated. I can provide more details if that would help.
