QVTKWidget does not work well with compiz
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When multiple QVTKWidget are used when using the compiz window manager (Ubuntu 8.10), very weird behavior is seen: On resizing one or more of the QVTKWidget stops responding. Sometimes you have to resize once, sometimes often for this to happen. Sometimes the whole desktop blocks before a resize is completed. When a QVTKWidget stops responding, clicking on it makes the complete desktop flicker once. When the window special effects are disabled (Ubuntu then switchs to a non compositing window manager) the QVTKWidgets work fine.
