I'm not quite sure, but I guess the optical barrel distortion effect is meant, which tends to reproduce large rectangular structures into barrel-like geometries - depending on the lithography equipment used. This could increase the intended capacitances a little bit, the effect increases non-linearily with increasing structure size. If this should be a pb., compose all caps from (integer) numbers of smaller caps of the same size - which is good practice anyway.
