corrupted image in firefox

Now I found a good example of this corruption. When Firefox displays a large
image it is frequently filled with garbage, and due to the size of the image,
it is clearly visible that the garbage is the remnants of previously displayed
images. I think the newly created surfaces in texture-from-pixmap operations
are not flushed properly. Or something like that.

In the attachment

should be shown (don't worry it doesn't make any sense even in Hungarian).
The startled Misato is the actual desktop background (with the folderview
plasmoid in the upper left corner), the '1' in the green circle is a frame from
a recently played youtube video, and some of the other garbage are also
identifiable.

After a few tab switches this image got clear, but doing a back-forward on that
tab made it filled with different garbage. I think redrawing the image clears
it, and a realloc leaves it uninitialized again.
