title: Strange color in today extension
body: <p>In iOS 10 I sometimes can notice strange colors of UI elements. You can see that some labels on screen are black. Sometimes UIImageViews are pink or red. I don't set the color of these views, but after 1 or 2 seconds after first loading the color changes and everything is ok.</p>
