Loading bar too small in OS X El Capitan (Beta)

I just installed Beta version of OS X El Capitan
And I was downloading the versions of Minecraft
And I saw that the loading bar was too small for the text!
Maybe it's not your fault, Mojangstas, maybe you can't do much about it
Maybe it's ot worth doing an Update just for that...

Well now you know.
(Sorry if this is a Dupe :-P)
