Does appdesigner support retina displays?

As you can see from the image below, the axis created in the app designer is not crisp. Normal plots created with e.g. plot(1:10) render as expected.

Does the entire appdesigner window appear fuzzy or is it just the plots?

And note the MATLAB in general (including appdesigner) should work for versions 2015b and higher.
