clear() not working with reduced palette

Which target device(s) and is it the same on a real device?

Fenix 7x, and I haven't tried it on my real thing yet. I hope to soon.

Yes, it happens on the actual watch too.

It seems to be a real bug. I haven't received any more responses on this here, do I need to submit a bug report?

Do you try something like this?

dc.setColor(-1, -1);

dc.clear();

I've tried both:

dc.setColor(Graphics.COLOR_TRANSPARENT, Graphics.COLOR_TRANSPARENT);

dc.setColor(Graphics.COLOR_RED, Graphics.COLOR_TRANSPARENT);

if buffer options is this:

var BBMOpts = {
:width=>Size,
:height=>Size,
:colorDepth=>1,
:palette=> [
Graphics.COLOR_RED
] as Array<ColorValue>};

it doesn't clear. Drop the :colorDepth and :palette options and it works.

so do you want to use transparent for any special effect or you claim that clear doesn't work?

I use buffered bitmaps in one of my wf and nobody noticed me about problem so clear works well but I use

dc.setColor(-1, colour);

(not transparent as background colour).

Clear doesn't work. If I do a fillPolygon in the buffer after clear, the previous polygon is still there when I draw the next one. The take away is that all the graphics code works as expected when no palette is given when the buffered bitmap reference is defined / created. Adding a palette option with a reduced number of colors breaks it.

your should have 2 colours in palette and no colorDepth in palette option

var BBMOpts = {
:width=>Size,
:height=>Size,
::palette=> [

COLOUR_OF_TARGET_BACKGROUND,
Graphics.COLOR_RED
] as Array<ColorValue>};

dc.setColor(Graphics.COLOR_TRANSPARENT, COLOUR_OF_TARGET_BACKGROUND);

dc.clear();

I tried that too. I read somewhere in the docs that all reduced color palettes have the transparent color added automatically, so that apparently doesn't matter if you specify it or not. That didn't make a difference either. Specifying the number of colors or not doesn't matter either. It still doesn't work. Again, no palette works, ANY palette options of any kind breaks.
