Bruno, you are just right. Thank you.
I've started to check other viewers but then realized that there is much better way:

Fine:     convert -size 32500x200 xc: +noise Random noise.png && viewnior noise.png
Broken: convert -size 32800x200 xc: +noise Random noise.png && viewnior noise.png

It's not 100% clear for me why some SW is OK, but Hugin is obviously unrelated to the example above.
Also not sure why I caught it just now. I got a new camera recently, but it has the same 16 MP.
I'll leave more description here just in case.

* Windows 7 x64:
** IE11, Paint, built-in viewer: OK
** FF26: fail. Same problem with Linux ("image cannot be displayed ...")
** Qupzilla: fail. Recognizes image size but shows the blank page.

* Fedora 20 x64:
** Feh, Kolourpaint: OK
** Viewnior: fail (stripes at right)
** Qupzilla: fail. Stripes over all the image. Picture becames visible just while window resizing.
** Gwenview: fail with image fit to window (just cropped the extra part), OK with zoom.
** Okular: fail. Stripes over all the image.

Feh, Kolourpaint and Viewnior are linked with the same libpng16.so.16,
the problem seems more common. TIFF isn't tested much, but seems
similar.

Summarizing, I would add some notification about possible issues to
Hugin if some resulting dimension exceeds 32768 px.

Title:
  Panorama render artifacts in some SW with Hugin 2013

Status in Hugin - Panorama Tools GUI:
  New

Bug description:
  Duplicating from questions section (#241262)

  I've used Hugin 2012 for several months and it was just great.
  After update to version 2013 there is some corruption in the final panorama and it isn't visible in all viewers (may be related to some other part, not Hugin).

  Example is attached. Cropped and converted from PNG to JPEG, just to show the pattern.
  TIFF output has the same issue.

  I use Fedora x64 and such a broken images are displayed fine (no stripes, no problems at all) in KolourPaint or Feh, for example.
  On the other hand, Viewnior and ImageMagick show the stripes and Firefox just refuses to load the image with error like "the image cannot be displayed because it contains errors".

  The interesting thing is that image scaled down with ImageMagick
  doesn't have stripes if scaling coefficient is below ~0.95-0.96.

  Versions of the related packages:
  hugin-2013.0.0-5.fc20.x86_64
  enblend-4.1.2-1.fc20.x86_64
