As a workaround you can apply the style explicitly or through an ItemContainerStyleSelector.
RadTileList: Memory leak when removing items from the collection of ItemsSource of the RadTileList and then change any property of any of the removed items. Available in LIB version: 2017.2.605
The horizontal scrollbar disappears setting RadTileList's background to black and when Windows8Touch theme is used. Declined: By default the ScrollBar's Thumb in Windows8Touch theme is transparent black and it is expected not to be visible on black background. For customization of the ScrollBar see attached project: 1. Extract the Style and Control Templates for the ScrollBar and its components from the System.Windows.xaml 2. Modify the HorizontalThumb and VerticalThumb's backgrounds to any color different from black - e.g. MainBrush, which is white in Windows8Thouch theme, change any needed opacities in the VisualStates 3. Apply the style globally for your application in App.xaml or only to the needed controls - in their <Control>.Resources (including all its needed resources)
If there is only one tile in a group and its Visibility property is set to Collapsed, the group header does not disappear.
The fix will be released with Q1 2016 offical version.

I use RadTileList without any tiles grouping. But internally TileListPanel get top padding 30 px. So visually I got "hole" above the list. And i can't set margin -30 because i can't be sure about this padding. ItemsPanelTemplate with padding="0" don't work properly as described at http://stackoverflow.com/questions/23091182/layout-issue-with-telerik-radtilelist-control. I tnink that this top padding should be 0 px if there are no groups at tiles or no "TileGroup" elements are specified.
