after uprgade from 5.5.0 I see some issues with interface scaling.
2560 x 1440 (external monitor, notebook's screen is off)
In SoapUI 5.5.0 in the compatibility tab I set custom high DPI settings, override scaling - Application. And everything worked fine.
In SoapUI 5.6.0 with this compatibility settings fonts are OK, but icons are distorted and some text (like in groovy test step window "Script is invoked with log ...") takes several lines.
Without override scaling or with override scaling - System text and icon size are OK, but everithing blurry.
