I had a look at the LPM013M126C datasheet, and there is a color inversion mode that would cause exactly this behaviour (mentioned on page 19 of the linked document).
Maybe this is a communication issue? In that case, maybe we should forcibly reset the color inversion flag on every g.reset()

Happened again tonight. When I checked this morning, the clock had stopped at 22:21, colours were inverted.
The theme was still set to dark. I could change the color of the custom theme, but they were all inverted.
Everything was back to normal after a reboot.

I would very much prefer that. The more the app loader grows, the more time it takes to find your configurable favourites.
Fun fact - apps that were added to favourites before they became configurable still show up as favourites, but without the heart icon. So they will stay favourites forever.

Categories work, but for some reason some apps don´t have the favourites icon. Languages, AC-AC and Assisted GPS for example.

If there is anything (even a space) in the "search" field, the category buttons stop working.

Thanks! Since i got the watch last year, i only updated the firmware and apps via the app loader.

Not sure if this is related to the new menu, so i put it in a new thread:
Changing colors in settings>system>theme>customize is strange. It seems like selecting colors works, but the display always shows the same color. Just updated from .27 to .32, but the problem is still there.
I just played around with the color menu for a while, then i got a page full of error messages (debug info was "off"). After reboot, it told me storage was corrupted. After a few minutes, i ended up with a factory reset watch. The color menu still does not work.

I tried reinstalling settings and locale, but nothing helped. All other settings pages seem to work fine.

Firmware update seems to have fixed the issue, except for the menu.

Last night, my watch seems to have changed from dark to light theme. However, when i go to settings, the themes seem to have flipped internally.
When i select dark theme, the background is white.
When i select light theme, the background is black.
When i try to change color in the custom theme, i see the selected color in the menu, the watch vibrates when i change it, but the display does not update.
Firmware 2v12.27

I like it!

To those using ContourClock: Could you try this version and see if the issue is solved? Thanks!

I changed the code to this:

setTimeout(function() {
  setInterval(draw,60000);
}, 60000 - Date.now() % 60000);

I also put this line in draw() to measure the timing error:

g.setFontAlign(0,1).drawString(parseInt(((Date.now()+30000)%60000)-30000)/1000,g.getWidth()/2,24+18);

So far it has never shown more than 0.01s, which is good enough for a clock that updates every minute.

I changed the code to use interval instead of timeout. So far, it seems to be reliable.
I use only the battery level and lock widget.

I played around with the time on my phone, but it didn´t stop the clock.
BTW: Why do all clocks seem to use timeouts instead of intervals to update? I just changed

function queueDraw() {
  if (drawTimeout) clearTimeout(drawTimeout);
  drawTimeout = setTimeout(function() {
    drawTimeout = undefined;
    draw();
    queueDraw();
  }, 60000 - (Date.now() % 60000));
}

to

setInterval(draw,60000);

, which seems to do exactly the same.

ContourClock, I am the author of that clock.
Seems to be a problem with the app, I'll have a closer look tomorrow.

@nyxor: Do you use ContourClock as well? I am the author of that clock and have the same issue. My clock locks up occasionally, but unlock with the button has always worked so far, and when returning from the launcher the time is updated again.

The clock on my Bangle2 regularly stops when it it connected via Gadgetbridge. The watch still responds, but the displayed time is not updated. When i disconnect the phone, all is good. Does anyone else have the same issue?

I really prefer TouchMenu over the default settings page. For some reason though, it messes with my app´s own settings menu. As far as i know, TouchMenu just replaces the built in E.showMenu with some custom functions. My app does not use E.showMenu, but somehow parts of the TouchMenu are still drawn. Here is my settings code:

(function(back) {
	Bangle.setUI("");
	var settings = require('Storage').readJSON("contourclock.json", true) || {};
	if (settings.fontIndex==undefined) {
	  settings.fontIndex=0;
	  require('Storage').writeJSON("myapp.json", settings);
	}
  savedIndex=settings.fontIndex;
  setWatch(function() {          //save changes and return to settings menu
    require('Storage').writeJSON("contourclock.json", settings);
		g.clear();
    back();
  }, BTN, { repeat:false, edge:'falling' });
  Bangle.on('lock', function () { //discard changes and return to clock
    settings.fontIndex=savedIndex;
    require('Storage').writeJSON("contourclock.json", settings);
		g.clear();
    load();
  });
  Bangle.on('swipe', function (direction) {
		g.clearRect(0,24,g.getWidth()-1,137); 
		var fontName = require('contourclock').drawClock(settings.fontIndex+direction);
    if (fontName) {
			settings.fontIndex+=direction;
      g.clearRect(0,0,g.getWidth()-1,16);
			g.setFontAlign(0,-1).drawString(fontName,g.getWidth()/2,0);
		 }
  });
	g.reset();
	g.clear();
  g.setFont("6x8:2x2").setFontAlign(0,-1);
  g.drawString(require('contourclock').drawClock(settings.fontIndex),g.getWidth()/2,0);
  g.drawString("Swipe - change",g.getWidth()/2,g.getHeight()-36);
	g.drawString("BTN - save",g.getWidth()/2,g.getHeight()-18);
})

Thats what I did at first, it has the advantage that you can easily adjust the line width by changing the offset.

Thanks a lot! One more problem: The drawClock function needs a font module. if i put

require("FontTeletext10x18Ascii").add(Graphics);

in the main clock code, the font is loaded and works in drawClock. The same code does not work in the settings app, i get

Contour Clock settings error: Error: Error: Module FontTeletext10x18Ascii not found
Loading the font in the library does not work either, but does not produce an error message...

Right, i was thinking of an eclipse...

Here is a version for filled rectangles. Performance is roughly the same, faster for r<=12, slower for larger radii. Performance is an issue here, on my Bangle2, "bFillRoundedRectangle(10,10,160,160,13);" takes about 85ms. For UI use, i think a LUT for rounded corners would be the best approach. All coordinates needed for a circle covering the complete screen would take up just 52 bytes.

 function bFillRoundedRectangle (x1,y1,x2,y2,r) {
    var f = 1 - r;
    var ddF_x = 0;
    var ddF_y = -2 * r;
    var x = 0;
    var y = r;
    g.fillRect(x1+r,y1,x2-r,y2);
    var cx1=x1+r;
    var cx2=x2-r;
    var cy1=y1+r;
    var cy2=y2-r;
    while(x < y)
    {
      if(f >= 0)
      {
        y--;
        ddF_y += 2;
        f += ddF_y;
      }
      x++;
      ddF_x += 2;
      f += ddF_x + 1;
      g.drawLine(cx1-x,cy1-y,cx1-x,cy2+y);
      g.drawLine(cx1-y,cy1-x,cx1-y,cy2+x);
      g.drawLine(cx2+x,cy1-y,cx2+x,cy2+y);
      g.drawLine(cx2+y,cy1-x,cx2+y,cy2+x);
    }
  }
