yeah, strange.. the effect happens actually on any simple
blur... looks like the gaussian blur is not really spreading
uniformly, but more "boxy". boosting the quality level
doesn't help either. ironically, if you switch the filter to
box it gets more like a circle.
also, if i replicate the same setup in shake, it looks like
a circle in 8 and 16bit, but gets wonky in float. so maybe a
gaussian blur is tricky to do in float?

Hi Randy,
Still wrong on my end... :-(
Played with Blur11 - didn't seem to make any difference.
Thanks for trying.

Merry Xmas its fixed. The weird thing is that fixing was
to turn off crop
to format in the blur11 then turn it back on. ????? So
I don't know.
strange. maybe it was holding onto the format from pre
crop some how for
whatever reason.
