    Description

      When scrolling a QGLWidget in a QScrollArea then it can cause another part of the application to appear corrupted. This happens if DirectRendering is turned on for the QGLFormat, if it is off then this does not happen.

      In the attached example, scroll the widget in the bottom right and you will see that it invalidates the drawing in the QGLWidget in the dock above it.
