Short description of error
I understand if this is an "as designed" (in which case I'll put this as suggestion on RightClickToSelect), but in case it's a bug:
Viewport Render does not render all 4 panes of Quad View, just renders 3D POV Pane
Exact steps for others to reproduce the error
New Default
Switch to Quad View (Ctrl Alt Q or [3DView] View / Area / Toggle Quad View)
Viewport Render Image ([3DView] View / Viewport Render Image)
