For some strange reason, when I use the VS and click the wheel to go up or down nose, after just two clicks, in either direction, the wheel speeds off uncontrollably making the aircraft totally unstable.

This occurs in all planes.

Is this a bug in MSFS2020 or on my end?

If it's on my end, what would be the fix ?

Thanks in advance.

I just did a flight in the TBM and VS worked fine.  

It appears to be a bug affecting some people, but not everyone. Workaround is to use the mouse scroll wheel to make changes. Point at the dial you want to change so that the mouse cursor changes, then use the scroll wheel. Note that you do not have to be on the left or right side to turn the dial in the appropriate direction. Just pointing at it will do the trick. Scroll away from yourself to go clockwise, towards yourself to go counter-clockwise.

I for one am not having to use the scroll wheel.  I use the left mouse button and count my clicks.  Each click for me appears to be equivalent to approx 100 fpm.  It does take a half a minute or so for the VS or FLC rate to settle in, and the rate does change during climb or descent, so needs adjustment much like power settings.  Both must be revisited at intervals. 

Make note to use FLC for climbs, and VS for descents.

To each their own, as they say. 😉

I've been mainly flying the FBW A320NX which has quite a few knobs to twiddle. I find it much easier to twiddle them with the scroll wheel. Particularly if the cockpit is bouncing around due to turbulence. I also changed scroll wheel zooming while in the cockpit to press the wheel and scroll, but I rarely need to zoom as I changed all my cockpit views to just the number keys without the CTRL. I don't use the number keys to do the ATC stuff.

I'm not even sure if I'm one of those with the issue as I haven't clicked on a knob in ages.

The runaway knobs is an issue I saw in Alpha\Beta testing and it shows up intermittently in the release version.

I fly only GA at this point.  Flew > 4,000 hours in commercial airliners in sublogic's Flight Assignment:ATP during the 1990's as a founding member and chief pilot of the first VA, Sunair, founded on Prodigy, later migrated to Compuserve and then the web. My business career mostly sidetracked me from 1999 until mid-2009.  Did not have available time to fly twice weekly VA routes.  So during the years since 1999 I reverted to GA and am totally satisfied with that.

Ah Sunair! That brings back memories!
