Bug#790359: eog: 6000x26000 image doesn't display, even controls not displayed

[Manuel Bilderbeek]

Package: eog
Version: 3.16.2-1
Severity: normal

Dear Maintainer,

I was trying to view a PNG with the following properties:
05_Xak_2_-_Het_Kasteel.png: PNG image data, 6000 x 26000, 8-bit/color RGB, non-interlaced
(it can be downloaded here: http://www.msx.org/downloads/xak-ii-map )

After a while, eog shows up, but the whole window is black. Even all icons and other controls are not displayed, mostly black.

The zoom level doesn't seem to influence this.

Moreover, although you'd expect a RAM usage of about 6000 x 26000 x 3 bytes, it's much larger:

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
 1107 root      20   0 8988,8m 1,243g 640,3m S   0,0 15,9   2:34.42 Xorg
 3874 manuel    20   0 9151,2m 1,048g 619,0m S   0,0 13,4   0:06.30 eog

and after closing eog:

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
 1107 root      20   0  201,9m  83,6m  45,2m S   1,3  1,0   2:35.73 Xorg

So, it's looking like eog isn't working very efficiently with RAM at all...
