Widget turns on/off with every button press in menu (LCD-Mode 'doublebuffered')

As the topic: in LCD-Mode 'doublebuffered' the widget bar at the top turns on and off, every time any button is pressed. Why the menu doesn't fill the whole screen? Is there a solution or workaround?

Minimum example:

Bangle.setLCDMode("doublebuffered");

Bangle.loadWidgets();

let menu = {
  "": { title: '--- DUMMY ---' },
  "Foo": 'Bar',
  "Exit": function() {
    E.showMenu();
  }
};

setWatch(function() {
  E.showMenu(menu);
}, BTN2, { repeat: true, edge: 'rising'});

Bangle.drawWidgets();
g.clear();
g.flip();
E.showMenu(menu);

Hi - I'm afraid widgets don't work in double-buffered mode, because they're only expecting a single buffer.

You can hack around it using:

Bangle.drawWidgets();
g.flip();
Bangle.drawWidgets();
g.flip();

But every time a widget changes after that, you'll get flickering.

You can use a memory-based buffer with Graphics.createArrayBuffer though, and copy that to the screen when you're done (there are a few examples in BangleApps). The widget bar will then work fine, plus it'll be right at the top of the screen

Hello Gordon. For the rest of the application the widgets work very well. They only cause problems when drawing the menus.
