Problem when painting complex polygon (Polyygon, Ellipse or Rounded rect) in widget with WA_PaintOnScreen set to true
I reproduce my problem on the Basic Drawing Sample where I just set the flag WA_PaintOnScreen to true for the RenderArea widget.
When I run the program throught an X Server, the widget is not properly repainted when another window is moved over it in the following conditions:
Deactivate Antialiasing Select a complex polygon (for instance polygon) Select a solid brush Move a window over the RenderArea widget
You can see on the screenshot that the polygon is not properly painted
Note: QT_GRAPHICSSYSTEM is set to native
Any idea ?
Thank in advance,
