When my jit.qt.grab object receives a "bang", it outputs not a "fresh" frame, but the one recorded when it received the earlier "bang". This means that, the output of my jit.qt.grab i always one entire frame-time delayed. This is even the case, when i set the metro to "bang" every 1000ms. It still sends out the previous frame. Is this normal? Has anyine got the same problem?
