    • Environment:
      I am using a notebook with a hybrid graphics card configuration (An Asus UX32VD with an Intel HD4000 and a Nvidia 620M) and am running the applications using "optirun [binary]".
      My OS is Ubuntu 13.04 64bit.

      Description

      When resizing a GLWidget or OpenGLWindow running on Bumblebee (in order to use my dedicated graphics card), the rendering draws only to the old area (see the screenshot). This can be reproduced using the Qt examples (I tried "boxes", "hellogl" and "openglwindow").

      Resizing without Bumblebee (using my embedded graphics card) works fine. Other applications like glxgears or qtcreator also work fine when using Bumblebee.

      Bumblebee starts its own X server in the background and then copies the rendered window contents to the main display. I assume there are problems when communicating with Bumblebee's X server. However, I have no idea how to investigate this.
