      Description

      Steps to reproduce:

      • set QT_AUTO_SCREEN_SCALE_FACTOR=1
      • Run qtquickcontrols\examples\quick\controls\texteditor

      Note:

      • FreeType looks even worse.
      • Same happens when setting QT_SCALE_FACTOR=2 on HighDpi or normal screens.

      Note: It does not really matter whether High DPI scaling is active. It is sufficient that QT_AUTO_SCREEN_SCALE_FACTOR is set for the below described initialization order problems to occur.
