Duplex UISlider.on_change() not always fired


i noticed that when at the turning point of a slider/knob movement, on_change() misses out one value change.

This is what i mean:

Say i am at value 10 and move my knob to value 11. on_change() is called.
Then i move to value 12. on_change() is called.
Now i move opposite, back to 11. on_change() is not called.

Is this a known issue?

No, it wasn’t, so thanks for noticing!

This will be one of the first things to fix in an upcoming release.
