Component used: Renderer.GlesRenderer
Version used: 1.0.1 / 1.1.0-alpha03
Devices/Android versions reproduced on: Galaxy Watch 4 / R890XXU1EVA8

The shouldAnimate method does not work correctly for the GLES render. If the watch state is changed to ambient (isAmbient=true), I want to continue drawing for 500ms to do an animation. So I return true until the time is over. The render method is called correctly, but the screen content does not update. Below is a code that illustrates this. I set the delay to 10s in the example, so that's easier to identify the issue

  var ambientModeStartTime=0L
  var isAmbient=false

  override fun shouldAnimate(): Boolean {
    val default=super.shouldAnimate()
    if (watchState.isAmbient.value!=null) {
      if (watchState.isAmbient.value!!) {
        if (!isAmbient) {
          Log.d("GDApp","staring ambient at ${System.currentTimeMillis()}")
          ambientModeStartTime=System.currentTimeMillis()
        }
        isAmbient = true
        if ((System.currentTimeMillis()-ambientModeStartTime)<10000) {
          Log.d("GDApp","continuing drawing at ${System.currentTimeMillis()}")
          return true
        } else {
          Log.d("GDApp","returning default at ${System.currentTimeMillis()}")
          return default
        }
      } else {
        if (isAmbient) {
          Log.d("GDApp","stopping ambient at ${System.currentTimeMillis()}")
        }
        isAmbient = false
        coreObject?.executeCoreCommand("setAmbientModeStartTime", "1000000");
      }
    }
    return default
  }

  override fun render(zonedDateTime: ZonedDateTime) {
    if (isAmbient) {
      Log.d("GDApp","transitioning to ambient at ${System.currentTimeMillis()}")
    }
    if (renderParameters.drawMode==DrawMode.AMBIENT) {
      Log.d("GDApp","in ambient at ${System.currentTimeMillis()}")
    }
    GLES20.glClearColor(Random.nextInt(from=0,until=255).toFloat()/255.0f, Random.nextInt(from=0,until=255).toFloat()/255.0f, Random.nextInt(from=0,until=255).toFloat()/255.0f, 1.0f);
    GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT);
  }
