I think I understand it, although not everything.
Sometimes panoramas (especially taken in HDR - stacks of 3 photos with
various exposures) look like this - there are lighter and darker areas in
the sky at the stitching edges.
I think it may be a result of taking HDR photos from the hand, every photo
is a little moved. (I use don't align stacks).
But the same panorama from the basic photos (the first exposure only,
without the stacks) looks a lot better.
It is difficult to say, this could be vignetting, I would normally
deal with this sort of low frequency pattern by increasing the
number of enblend levels.

Hugin-ptx is a mailing list with a web-interface, you can't edit

I finally forgot to ask:
When making panoramas from stacks of HDR images
should I use exposure correction or reset all photometric parameters before
stitching?
because after exposure correction all images look the same.
The Hugin Stitcher tab should do the right thing here: when using
the Exposure Fusion (with enfuse) option, Hugin resets exposure for
all images, so you don't have to; when you are merging HDR stacks
you do want the photos to be aligned for exposure, so Hugin applies
exposure correction.
So in general, you should optimise exposure for photos.
