Not sure if you read this entire thread in detail. – This is a known issue with an already known solution on the way.
Specifically my old post, showing that it’s related to the input midi message being echoed back with some latency: Midi "ghosting/Jitter" Cubase 12 with midi controller encoders (Midi Remote Control) - #5 by Nico5
And Jochen already replied, that a solution is on the way, via being able to suppress the echoing:
p.s.
Yes, because scale will make the target controller respond more gently until it crosses over the current internal Cubase value. Once it has crossed over, it will be the same as jump.
Yes, because when that dialog is open, the messages don’t get passed to Cubase and thus no echoing of the message occurs. Also see this post by Jochen: How to change MIDI Remote MIDI port after creation? - #8 by Jochen_Trappe
