What is your host system?

If you're on a mac is it Retina?

If you're on windows, what dpi setting are you using?

As I've mentioned, it is both on Linux and Windows (I don't have a mac so I can't test that).

My Linux laptop LCD has 96dpi, and external screen probably higher (I'll check in the evening).

The Windows was another machine, also 96dpi.

However I don't see how that could be DPI related considering with the "correct" size it is rendered correctly.
