Workflow to reproduce 1 (transparent background in PNG):
Fire up Cubeviz. Load the data in example notebook.
Export Plot -> Export to PNG
Save the file, then open it up in your favorite image editor like Photoshop. See that the background of the axes is transparent, not white.
Workflow to reproduce 2 (invisible axes in MPEG-4):
Fire up Cubeviz. Load the data in example notebook.
Export Plot -> Export to Video
Just a few frames is enough (say, 10).
Export to MP4. Then play the video with your favorite movie player and see that axes are not visible (black text on black background).
This is not a problem for standalone app (viola) dark mode, or any mode in regular notebook/lab (non-viola) usage.
Maarten suspected that this is caused by some CSS viola/bqplot is using for the standalone mode. @maartenbreddels or @mariobuikhuizen should investigate upstream.
