    Description

      I am on windows, using Qt 4.6.3 with DS9 backend. I use the pre-built release of Qt for MSVC2008.

      I have a Phonon VideoWidget inside of a QGraphicsProxyWidget added to a QGraphicsScene. I have a QGLWidget as my viewport for my QGraphicsView.

      When I rotate the widget to an angle that isn't divisible by 90 degrees it causes really big slowdowns. The easiest way to replicate this is to rotate the widget 45 degrees.
