- Qt does not automatically scale even when AA_EnableHighDpiScaling
  is set. For the best UI at high scaling ratios, UI dimensions should
  be multiplied by the scaling ratio manually. For instance, Qt
  accepts pixel values only for border-radius, and any stylesheets
  with that property, would need to be manually calculated and
  re-propagated. This patch will allow windows to render a fixed size
  window, slightly blurry.
