Trackpoint jumpy on bluetooth

The tracepoint on Bluetooth is very very jumpy, so much so that I am not sure it is useable. Anyone any suggestions so that they can work properly? Trackball and trackpad are okay.

Suggestions for configurations?

Which firmware?

16.3.0 — modules and keyboard (the modules were updated on one of my UHK 80)

Is it behaving same with 16.2.x?

Do logs say anything? Do they say anything after you set devMode true in $onInit?

How jumpy is jumpy? (What is your eyeball on the cursor update interval?)
