main UI should flip to Performance when system is set to high DPI

Main UI does not flip to Performance when system is set to high DPI, you get a 2nd window!

 

set to 125 %  = to high DPI on 64 bit win7, screen is 1440 x 900

 

It would be great, if main UI flips to Performance even when system is set to high DPI, like it does with DPI 100%.
