I'm still downloading the PNG file, but I noticed that it is 
33352x4696 pixels.  This is big but it should be fine with PNG.  The 
Vigra library used by Hugin/enblend has a hard limit of 2 
gigapixels, and different TIFF libraries have a 2 or 4 gigabyte 
filesize limit, but you are nowhere near this.

Is it possible that your image viewers only support a 32768 (2^15) 
pixel maximum dimension?  This would explain the artefacts in the 
right hand side of the image.

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
