MyPaint version: Version 2.0.1+git.478280f2
OS: Windows 10
I would like to fill an empty palette slot by picking a color. So I double click my slot to open the “Color details” window. There I can find a color picker tool (refered as “eyedropper” here), which should be very convinient for that task. Unfortunately, the mouse pointer disappears at the moment I click the eydropper button. This prevents me from selecting my color. So the task cannot be done.
