When left alone (no other user input) both displays (waterfall and panadapter bandscope go into hyperdrive. It is a very active and fast jitter. the waterfall, rather than being a constant scroll has bands of unredrawn lines. What's odd is this has happened twice when I've been away from the laptop. When I've returned and noticed it, just moving the mouse seems to allow it to settle down eventually. It has happened twice since I've upgraded. I did reboot both pc and 6500. I did have an initial issue with DAX ch 1 but after toggling between ch 1 and ch 2, channel 1 started to show audio. After the initial post it occurred again, large areas of black (unpainted lines) in the waterfal and the bandscope was jittering worse than.....well, fill in the blank. This never happened with 1.3.0 or earlier.
