If scaling is set to higher than 150 % preferred 200% simple drawText() of Qpainter crashes.
Atttached example reproduces it:
1. Change the display properties of at least one monitor to include scaling:
-> e.g.: Start Menu -> Settings -> Display -> Scale and layout -> 200%
2. Run PainterCrash.zip
3. Notice the application crashes on the call to drawText()
4. Also note, calling drawText() with a non-whitespace character works.
