Remarks
When you enable per-pixel opacity, the system no longer draws the non-client area. This is because the intended purpose of UsesPerPixelOpacity is to show non-rectangular top-level UI that works in interoperation scenarios. Therefore, showing the rectangular non-client area defeats that purpose.
