Summary     : Simple Image Viewer for KDE
Description :
Gwenview is a simple image viewer for KDE. It features a folder tree
window and a file list window, providing easy navigation of your file
hierarchy.
Distribution: openSUSE 13.2


Reproducible: Always

Steps to Reproduce:
Display attached image with Gwenview. Since the application defaults to rescale-to-window, set image scaling to 1:1. Observe the colour of the pixel at coordinates 1313,892 relative to the top-left corner of the image.

Actual Results:  
Colour is white.

Expected Results:  
Colour should be a deep blue.

This bug does not occur with Opera 12.16, Chromium 39.0.2171.65, gifview (from gifsicle 1.87).

When the GIF frame delay is changed from none to 1 centisecond each, Gwenview renders the pixel correctly.

GIF with 1 centisecond frame delay each

File contains the same encoded image data as above, just the frame delay is different.

I can't see where to get the pixel coordinates in Gwenview.

Are you able to confirm if this is still an issue in current Gwenview?
