From Ubuntu Trusty and all other gtk 3.10 based distros, HIDPI settings will supported.

We should respect them in MIxxx as well.

HiDPI support has not creped to Qt 4 by now.

So there is only th poor man solution to hack up the legacy string parser to multiply all size values by 2.
The other solution would be to provide dedicated HiDPI skins.

I would prefer to hack up the legacy string parser, if one needs it very hard for 1.12
Later versions of Mixxx will probably base on Qt5 with library support for HiDPI.

I would love to see it upgraded from "wishlist" as it makes Mixxx unusable on my portable device...

What are the specs of your mobile device?
Are you able to build the linked branch in #⁠5?

My device is a surface book pro, with a 13,5" 3000*2000 display.

I'll try to build it, it is the first time however I do this, so bear with me as building an executable might take some time :)

If it runs windows, you can download a build from:

I did not know you could do this :p
And it works quite fine! A *2,5-3 option (or even a numeric one) could be interesting however it is now usable, hurray =)
