Hi Jean-Sèbastien, Thanks ! :) It helped to use the TextureVisitor to disable unrefImageDataAfterApply. Have you tried to share the OpenGL context between the widgets to avoid several instances of all object resources.
The QGLWidet has the constructor QGLWidget ( QWidget * parent = 0, const char * name = 0, const QGLWidget * shareWidget = 0, WFlags f = 0 ) and bool QGLWidget::isSharing () const to check if the GL system was able to provide it. Is it possible to do the same with QOSGWidet?
