Problem with QGLWidget::renderPixmap over remote X11 (GLX)



  • I am having the problem that the pixmap returned by QGLWidget::renderPixmap() is just a black image. The GLX version is 1.2 (client 1.4, server 1.2) and the docs states that GLX 1.3 is required so this may be the reason. Normal rendering works fine however.

    How does renderPixmap() work? Is relying on features present in GLX 1.3 but not in GLX 1.2?
