High/Low DPI Adapting

The Qt UI would change the size according to the logical DPI of the computer
Only Windows and Linux have been tested. (Should also work on Mac but have not tested).
The function is unfinished.

Fixes #576 
So what are you attempting to test here?

It looks to me like you are setting the Minimum Size but then you are comparing the actual size of the Widget. You are comparing apples to oranges here from the looks of it.
