Thanks for reporting this -- I had noticed it quite a while back, but
never got around to filing a ticket.
If memory serves, the HPs have the same behavior as the 745s.
(For what it's worth, I was using ListPlot3D[] on some imported data,
but I expect that any Graphics3D object would trigger the bug.)
