DrawableButton "ON" draws dark frames over transparent parts

General JUCE discussion

Hi,
how can I avoid that DrawableButton draws dark frames over transparent parts if it is in “ON” state? All images for all states have been provided (does not matter whether a DrawableImage with alpha channel or some other Drawables are used).

It has a different background colour when on, but you can change it to transparent.

Thanks!
Thats it.
