[Qt-creator] Designer has unreadable tiny controls

[Nikos Chantziaras]

Opening a *.ui.qml file in Creator results in the Designer showing 
elements in the left-side panel using a very small size.

The problem was not there with a 1080p monitor. Now I'm using a 1440p 
monitor with high DPI and everything is pretty much unusable since I 
can't see much.

The rest of Creator, as well as the Designer for QWidget-based .ui files 
has no issue. Only the *.ui.qml Designer has this problem.

Is there something I can do?
