Hi,
when running qtcreator on plasma 5, I have noticed that the welcome view is seen as a black window.
If I change the widget style in "System Settings -> Application Style -> Widget Style" from Breeze or Oxygen to QtCurve, the wellcome window is seen again.
How could I check if there is a bug in the Breeze/Oxygen Widget Style?

The steps to reproduce the failure are:
- Open qtcreator
- Open any file in the editor.
- Open the welcome window.
- A black window appeares.
