Space navigator 3d mouse working in 2.92, but not in 2.93

When rolling on x axis, Navigator is now also zooming in y axis at the same time in strange jumpy steps.

Problem does not appear in 2.92. Recently updated Navigator driver - didn’t help.

Have checked that Blender preferences are set the same for INPUT / NDOF

Navigator’s settings are also the same for both programs.

Thanks for any clues.
