"None" colour and Paint Brush Tool in pixel persona

[Laganama 3]

I'm a bit confused with the behaviour of the "none" colour while brush painting in pixel persona. I can set the colour of foreground and background to "none", what is also indicated by the red diagonal line. This is fine until I choose the Paint Brush Tool and start to paint something. The colour of the foreground changes automatically to white indicated by the white circle, but the brush is painting nothing. Because before the sellection of it the colour was set to "none". But why is than the circle indicating white colour? Either it should stay indicating "none" (red diagonal) or it should paint with white colour. This would by logical, am I right?

Any suggestion about this?

That's interesting. The sequence to cause that seems to be:

1. Switch to Pixel Persona
2. Select the Brush Tool
3. Change the foreground/background colors to None
4. Create a pixel layer, manally or automatically via the Assistant.
5. Color circles turn white, but colors are really still None.

All you need to do is click the None button (circle with red slash) again, and both circles become None.

Or, just remember to create the pixel layer before you set the colors to None.

Seems like a minor bug. I'm not sure if it's one that's been reported yet.

Have you noticed this problem also directly at the Affinity live keynote? Just jump to the time 27:50 and there you are  The circle is showing white color but the brush isn't painting at all.
