2. Open Effects. (see attachment Win_Appearance_Effects.png)
3. Uncheck "Show window contents while dragging" 
4. Open any windows application and drag the window by title bar
5. User see window dragged showing only a dotted frame 
6. Switch to Firefox 
7. Enable the new "Firefox" button. 
8. Drag window by pressing mouse on right of "Firefox" button. 

Result
 User see window dragged along with contents

Expected 
 User see a dotted frame being dragged

This is fixed by the latest patches on bug 555081. Note, however, that if you use the Classic Windows theme, dragging will only be possible by the titlebar (dragging by the appbutton was just a side effect for a few days), until we enable custom titlebar drawing for non-aero themes, and this system setting will be honored.
