Would this kind of comparison in the ColorAppearance::wbCamChanged function be considered unreliable or otherwise undesirable? This didn't spam the history values in my quick test and ticking the checkbox both moved the slider and changed the applied value. It also seemed to fix the issue with Automatic Symmetric mode, where the applied value was forced, but moving the slider printed wrong values to the history.

[this, temp, tin, autotemp]() -> bool
        {
            if (temp != tempout->getValue()) {
                disableListener();
                tempout->setValue(temp);
                enableListener();
                listener->panelChanged (EvCATtempout, tempout->getTextValue());
            }
            if (tin != greenout->getValue()) {
                disableListener();
                greenout->setValue(tin);
                enableListener();
                listener->panelChanged (EvCATgreenout, greenout->getTextValue());
            }
            /*
            disableListener();
            tempout->setValue(temp);
            greenout->setValue(tin);
            enableListener();

            if(!autotemp) {
                listener->panelChanged (EvCATgreenout, "");//greenout->getTextValue());
                listener->panelChanged (EvCATtempout, "");//tempout->getTextValue());
            }*/

            return false;
        }

@kaesa

it works, it's another way - a little simpler - to achieve the result. I'm going to change it.
But, for the record, this "wbCamChanged" function, I have already disabled/enabled it several times.

In any case, thank you for this positive contribution.
