I have noticed the same behaviour with 2 different focusers (an Esatto2 and an Esatto3), with of course 2 different temperature sensors. Not only I see the defect with Kstars, but also with CCDCiel . The motor temperature is updated on a regular basis, while the outside temperature is stuck to its initial value.
I would tend to think the Indi driver is the culprit.
