If you put continuous animation at window (WPF Framework), then you minimize window, then go at Taskbar application button to view its LivePreview, animation at the preview is paused.

    This should be a system level by-design issue, cannot been resolved in an application level(WPF).Minimized windows don't have a client area to render on, so they can't play a video in the thumbnail. The system remembers the last snapshot of the window before it was minimized and uses that for the thumbnail.

    So, only DWM_CLOAK -> Restore window can maybe help to push DWM updates.

    Thanks!

    P.S. Hm...it is not then LivePreview ... better suited would be HalfLivePreview :D
