since upgrading to Ubuntu 13.10 I've a problem with image-corruption in firefox.
Symptoms:
1. A loaded image is shown instead of an other loaded image (image is duplicated / replaced) [see screenshot, the icon in the top-left "Meine Abos - Youtube" has the Icon of "IT-News ct, iX, ..." and of "Portal > ubuntuusers.de"]
2. A image is corrupted so you can't even recognize what shall be shown
2_1. The image is black either entirely...
2_2. ... or some pixels are repeated over the whole image [see attached screenshot, the icon in the top-left "Meine Abos - Youtube"]
This happens nearly every time, when the image is scaled down by firefox. It happens less often when the image is actually in the right size.
The problem can only be solved by reloading the image (preventing the cache, i.e. hitting ctrl+f5)
Animated images [gif] are never corrupted.
