Known issues

1. Partial Qt Hang (Waveform no longer updates, some Qt actions still work)
on one Windows PC with Intel graphics. Problem does not occur with
other widgets. We suspected an OpenGL issue. Unchecking the "opengl"
setting and changing min/max to lines works around the issue.
2. Undo / redo support is not working
