The firmware issue, that can be fixed, is about rotating the knob fast and it sometimes going backwards.
Also the sensitivity of the knob needs to be adjusted in the code, so that small adjustments trigger a change right away - to make it less “steppy”.
(neither 1.4 or 1.5 will change/fix this by the way)
Other oddities regarding the knob, besides what I mentioned, are likely hardware issues.

I have the same issue after upgrading to 1.4.0.448 (stable release)
But It´s present on the right knob.
Turning it fast clockwise it decreases the value.
i’m still noticing this (especially on the right knob, it seems), even with the replacement board you sent me, so it seems a software upgrade is required…
