The extended region breaking up is not a tuning problem. The model
places the source spanning one whole canvas axis - pad left/right and it
spans the full height, pad top/bottom and it spans the full width - and
the reference pipeline this LoRA ships with splits anything else into
TWO passes rather than doing it in one. Padding both axes and running
once puts the placement outside what the weights were trained on.
Verified on one image, one seed, changing only the geometry: padded left
AND bottom, the dress is cut off flat and the legs below it are mush;
padded bottom only, the gown continues full length with no seam.
Load Image + Pad happily pads any combination of sides, so this is easy
to hit by accident - and the usual cause is not a deliberate second pad.
Padding only the bottom of a 720-wide source at canvas_multiple 32 rounds
the width up to 832, and an 11px sliver breaks the span exactly as
completely as a deliberate 231px pad. The warning therefore reports the
spare pixels on each axis and names the multiple, instead of just saying
the placement is wrong.
