I'm helping a friend to implement an INDI/Ekos/kstars environment in his observatory.
Everything is ok except for the motion in the DEC axis when commanded from the "Mount Control" window.
Goto's motions, however, works great in RA and DEC.

The INDI/Ekos/kstars runs on ubuntu 20.04 (was tested before on 18.04).
The TSX runs in windows 7 (Home Premium) in a virtual machine (ubuntu is the host).
The latest indilib was tested as well as previous versions (compiled) back to 2019.
We also tested to run TSX on wine.
In all scenarios the problem is the same: no DEC movement from the "Mount Control" window.

There is also another strangeness in the "Mount Control" window: the slew speed options jump from 256x to 9x which is indeed faster than the 256x.

In the attached log we moved the mount first in RA with success then in DEC with no success.

Thanks in advance.
