Display error using font "Impact" (on mac)

Strange behaviour:
If I choose the “Impact”-Font (provided with OS X) it is being squeezed vertically, although no text-rendering-parameter has been changed.

You ca see the difference in this screenshot:

In the window you can see the correct rendering of Textedit.
Seems to happen with this Font only…
Maybe it’s because of its condensed style?

This looks to be a bug in Qt’s font rendering (Dorico relies on the Qt application framework). I have reported this bug to their developers.
