and a third bug in the device tiles:
If you turn OFF: ‘show widget’s background in play mode’ and then change the color of the device tiles: the background lines are shown (which is incorrect).
Moreover if you then turn ON: ‘show widget’s background in play mode’, then the background lines are NOT shown in the device tiles.
I do this with white background for the app and white background color for the device tiles.
and I also now realise that its strange that the ‘9th’ tile (which I described in the earlier bug) is gray when acting ‘normal’. It should be white!!
Note that if you set up the device tiles its shown correctly. Only AFTER you change the tile color AND you have ‘show widget bg in play mode’ OFF its is shown correctly.
