Blur Bug
We have found a situation, where (sibling) layers are causing the result of a `scale` transform to be blurry. Please have a look at the attached html file.
In the attached file, we used `translate3d` to force a layer. This can also be reproduced when using `position: fixed` instead. We have found out that adding a layer will also force a layer for the next siblings.
We can work around the blur by adding a new parent to the `scale` transform, so that the div containing the `scale` does not use a layer (in this case, the parent holds the layer).
Firefox and Chrome can render the text fine.
This is probably also the cause of <a class="bz_bug_link
