What happened?

If I add a dual marker to a large region and then zoom in, the Waveform widget no longer renders correctly.

zoom_dual_marker

The log file also contains the following warning:

ERROR:2024-07-31 16:54:39,007:waveform_widget.py:1443:joulescope_ui.widgets.waveform.waveform_widget:Exception during drawing

What was expected?

The UI should continue to render correctly.

How to reproduce?

  1. Add a dual marker, and expand.
  2. Zoom in far while keeping the dual marker in the view.
  3. Observe the behavior.
