Hi, I work on an opengl project in version 3.3 coreprofile. When I used a QPainter on my QOpenGLWidget I have an OpenGL error. In fact the QPainter used the QOpenGL2PaintEngine to draw the primitives. In OpenGL 3.3 a VBO and a VAO have to be bind. it's wrong with the current PaintEngine. There is a QOpenGL3PaintEngine ? Or How can I use the QRasterPaintEngine to blit my GUI on a QOpenGLWidget ? Regards, Robin

Hi, That's a question you should rather bring to the interest mailing list . You'll find there Qt's developers/maintainers. This forum is more use oriented.
