Bug#581891: eog: Sufficiently large images displayed incorrectly; repeating earlier parts of the image

[Josh Triplett]

Package: eog
Version: 2.30.1-1
Severity: normal

In doing some data analysis, I needed to work with some images of size
6000x$BIGNUM.  I found that beyond a certain size, eog would start
repeating earlier image data in place of later parts of the image.

I've attached a 6000x50000 grayscale PNG, large enough to demonstrate
the problem but still small enough to reasonably email.  The bright line
in the image should form a smooth curve, but it has a discontinuity
instead where eog starts repeating.
