Hello, Christian. If you overload the virtual function, QOSGWidget::paintEngine, to return 0, you may see improvement. In the past, that is what has worked for me, and the option has been discussed in this list. Do a search on the archives for paintEngine and/or Qt paint for more detail. Also, check out the Qt documentation and source code for possible implications for your project.
I hope this helps... D.J.
