    I have a strange problem with an application using Qt and OpenGL...
    (0_1521565653540_cas1.jpg

    when I switch to full screen (using the showFullScreen() function), the screen splits into two parts along a diagonal. On one side the display is normal, on the other, the display is completely black...

    Does anyone have an explanation for this phenomenon? The code seems to have no effect. Even if I disable all traces, the black triangle still appears...

    Best regards,
