    Description

      When running examples/xmlpatterns/trafficinfo the rendering result is inconsistent between graphicssystem raster and opengl. Please see attached screenshots for a comparison.

      It appears like a bug in the GL paintengine (I looked at MainWindow::paintEvent(QPaintEvent* in file "examples/xmlpatterns/trafficinfo/mainwindow.cpp")
      I have not found this in other demos or examples though.

      The rendering problem does not occur for graphicssystem raster.
      The Qt build was a release from the Qt 4.7 branch pulled on Tuesday, August 24.
