Firefox distorted large, scaled images

Hi everyone,

I have a problem with Firefox 3.5.5-1 (it persists in 3.6b5 from AUR) when zooming large images that extend beyond the screen.

Using this random test image: http://homepage.mac.com/tribe3/.Pictures/test.jpg my browser produces a correctly scaled partial image while loading it: but when its finished it switches to a completely distorted version of a part of the image: .
If I zoom in and display the image in its original size everything is fine.

Another problem that may relate to this are some small images (i.e. logo) on youtube .

I tested it with a new user, so it is not dependent on any addons or profile settings.
I am using the radeon driver with an x1800 mobile.

Does someone know whether firefox uses some library/non-mozilla code to display images and rescale them? Then I could test whether this is actually a bug with firefox or maybe some driver/X/etc. issue.

I searched and found no directly related problems and no similar bugs at the mozilla bugtracker, so maybe I should open a bug there. I think however that it is somehow related to my Arch install, as my Ubuntu 8.10 install does not suffer from this (using older Xorg/driver versions however).

Any hints on this problem? Anyone experiencing the same?

Same here. Using a Radeon X1800XT  with radeon driver and KMS.

Don't know where this does come from.

Has anyone found a solution to this? I have been having this problem for a long time but can't find a solution.

For the scaling problem, actually there is no solution yet.
If i wasn't wrong, in the past (years ago) mozilla pointed to a cairo issue.
