[TF-dev] Blue non-transparent corners

Hi everybody,
in the latest download page I have noticed that some localized versions of the hovered "Download" button have blue corners (e.g. in [1] and [2]) instead of transparent ones (e.g. in [3]). Maybe this depends on Robert's script that generated them?
Regards,
Filippo
