Version: 3.97.00 (KDE 4.0 RC2) (using KDE 3.97.00 (KDE 4.0 RC2), compiled sources) Compiler: gcc OS: Linux (i686) release 2.6.22.13-0.3-default Try to show a large image (larger than screen) 1:1. Then choose "zoom to fit". Scroll down and up using the mouse wheel. The display of the image will be messed up. (Probably Konqueror tries to scroll like in 1:1, which has to fail as the image is already fitting screen when using "zoom to fit") Konqueror should not try to scroll at all with "zoom to fit".
Checked this issue with kde 4.6.2, works properly here (no messed up image while scrolling a large image (larger than screen) with the mouse wheel, with "zoom to fit" the mouse wheel does not scroll). @Vinzent: Please try with an uptodate kde if it is also solved for you.
This is indeed fixed.
