I zoomed a capture, than captured next buffer. When I scroll the buffer, the data before and after the current page is not drawn.. The following pictures explain better:
I captured while zoomed:
After left scroll
After right scroll
As you can see, in the Zoom Overview, the buffer looks correct. Also serial decoder decodes correctly as well. Which means signal before and after the visible portion are captured correctly.. However the graphics outside the visible range at the time of capture is now drawn..
If a PicoScope is still running it is not possible to read out detailed data from the scopes buffer, and changing the zoom region will not refresh the main display.
I can confirm to navigate I have to stop the capture.. I can also add that when you zoom in the zoom trace is not as sharp as it should be..

Does that mean that device only sends data just enough to display but the whole buffer while running a capture?
But it is still capturing non-detailed data then. Why not draw it instead of blank? You already have some sort of min/max style "uncertain" trace sometimes used in ETS, waiting for detailed data etc. Would prefer dashed line(s) however (bordering "uncertain" region).
We only collect enough data, the rest of the data remains on the device in the waveform buffer, this helps to ensure a minimum rearm time between buffers.
