    Description

      This bug does not exist in Qt 4.8.4, it appears to have been introduced in Qt 5.

      I have text rendered into a QGraphicsScene. When I go to render it to pdf, the spacing between the letters is extremely wrong.

      I have also observed this when rendering the text directly using the QPainter call but that's harder to demonstrate.

      I've attached a small program that demonstrates the issue and the two pdfs generated in 4.8.4 and 5.02.
