Created attachment 472 [details] screenshot, lower half of trace shown How to reproduce: Load the file, zoom in by means of a pointing device's scroll wheel or a touchpad's scroll bar (to zoom in but keep the vertical position which the software assigned to the trace). $ pulseview -i ../sigrok-dumps/misc/basic_analog/sine.wav Only the lower half of the analog trace is seen. Users can manually move the trace into view.
