https://sourceforge.net/p/pgfplots/bugs/130/attachment/Test_Surf.pdf When trying to use the layers feature combined with the enlargelimits option, surface plots are shifted away from their original position and aligned to the top right corner of the axis. This only happens, when compat is set to 1.8 or newer, with 1.7 everything works fine, as you can see with the exaple below.

Thanks for the detailed report... It appears to be related with shader=interp.

I can reproduce it and I will look into it.

I can narrow down the problem to "clip path=upper bound"; a feature that was introduced with 1.8 and which becomes active as soon as one writes "compat=1.8".

If you write

\pgfplotsset{compat=1.8, compat/BB/1.7}

in the first example, the displacement is gone.
