UI not displaying properly in Safari 7.1.8

Screenshot of the affected page(s) attached.

Thanks for letting us know. I’ve reported this to our developers and I’ll let you know as soon as I have more informations about the issue. Thanks for your patience!

After upgrading to Safari 9.0.1, the page seems to be working again.

Great, thanks for updating the Safari to newest version. We were going to suggest you the same thing.

However, I have noticed that, even in Safari 9.0.1, the UI is much slower to load and to respond than it is in Firefox.

Furthermore, some elements simply fail to load.

Can you please try to clear your browser’s cache and try again? Screenshots of how UI looks when you load it on Safari 9.0.1 would be helpful too.
