    Description

      I am using Qt 4.7.1 on OSX 10.6 and I am having trouble with redraw flicker when putting QGLWidget in a QSplitter.

      The following code shows how to reproduce the problem.

      When moving the first handle, the background (splitter/mainwindow) redraws in gray/white before the QGLWidget redraws in black. With a QWidget, the problem is not visible.

      I have added a second splitter inside the first splitter to show of this redraw latency adds up when moving the second handle.

      I don't known if this is a bug or if there is a solution.
