Copied from my post on Arch Linux bugs:
With gpicview, I open an image with a higher resolution than the gpicview window's. I click the button to view it at 100%. I can't scroll the image to view the bottom of it (or the right edge if it's wider than the window): when I use the mouse wheel or drag the scroll bar, the image immediately jumps back up to the top (or left) (even though the scroll bar shows it's showing the bottom (or right)). With a PNG that has a transparent background, the image smears when I drag the scroll bars.
I reinstalled gpicview-0.2.1 and no longer had this problem.
