IPR
doesn’t respect image plane display options. When updating, IPR
displays the image plane in the background though the image plane
is set to none.
Workaround
Delete the image plane.
Manual feedback from IPR
Manual updates are needed to get feedback from
IPR when making changes to:
image
planes

maps due to light location changing, depth map resolution changing,
or the auto focus changing
tessellation
Workaround
Redo the IPR render after these changes (or select IPR
> Update Shadow Maps).
