Bugs and quirks

 * Some devices have a chance of crashing with a BSOD upon resuming from hibernate if booting from eMMC storage.
 * The update process to this build has a chance of hanging for extended periods of time.
 * Both the documents and downloads sections in the privacy settings have broken icons, and as such, rectangles show up where the icons are intended to be instead.
 * Taskbar preview thumbnails sometimes do not render consistently. If this happens, a blank area will be shown instead of the thumbnail.
