The problem with this kind of images is that the images seem to render in a "slow motion" of sorts.

I would like to know how to avoid

I see that an animating button leaves a trail. This doesn't happen in Chrome.

Same to me. The picture from the previous frame does not seem to be cleared.

Same as bug 246792.

This is a bug in a system framework below webkit.
