I just opened AM for the first time on my new laptop. Its a Dell XPS 15 with a rather high density display (3200x1800). The display is comparable to what Apple builds into their Retina Macbooks and is very nice.
To avoid everything on the display being tiny tiny tiny, Windows (Windows 8.1 in my case) as well as OS X uses a system scale function. This is supposed to scale everything on the display at a definable factor. I use 150%.
Unfortunately Audiomulch doesn't really seem to be affected by this system scale factor, so the GUI remains crazily small and not really convenient to use.
Is there any chance to get AM DPI aware in a future version?
