eog corruption when drawing wide image at 100% size (59.39 KB, image/png)

Description Martin Olsson 2009-08-24 11:07:01 UTC 
1. download this 17MB png file using wget:
http://www.kernel.org/pub/linux/kernel/people/gregkh/kernel_history/developer_graph-2.6.22.png
2. open it in eog. thumbnail renders fine. zoom once and it still renders fine.
3. then press "view in 100% size" and scroll around. now it no longer renders fine. the image becomes blocky due to severe repaint issues.

43K pixels is not that big really, high end digital cameras can produce even bigger images so while it's understandable that eog's PNG decoder take a while to process this image at startup I don't think it should show a corrupted image.

Note: i'm using eog "2.26.1-0ubuntu1" on ubuntu karmic.

No, just scroll further to the right and see how it is cut off after ~3/4 of the way. This is likely another incarnation of bug 303698 and bug 163090.

It comes down to gdk-pixbuf having troubles with images larger than 32K in any of the two dimensions.
