I've a problem with the QGLWidget. I've my QGLWidget as a central Widget of a QMainWindow. Because I need high screen resolution I put a scrool bar to go up and down in case the space of the central widget is smaller than the resolution I need.
The problem is that when I render my scene, pixels which are not visible from the central widget are not processed. Figure 1 of the attachment shows the result when the scroll bar is up. The bottom of the image is not processed (the not processed region is the region which is not seen in the central widget). In Figure2 I scroll down and the result is the whole image processed (int this case the pixels not processes are from the above region, but because there's no pixel to be processed there's no difference).
I really don't know why this happens. Is an openGL problem or is a QGLWidget problem? I tried compiling with the DEFINES += QT_GL_NO_SCISSOR_TEST but it still doesn't work.
