The default value of `nbagg.transparent == True` unfortunately means that full images are always sent for every frame.  This results in lower framerates and flickering.\n\nI can workaround this by setting `figure.facecolor: white` and `nbagg.transparent: False`, but I wonder if we shouldn't make this the default.  2.0 might be a good opportunity to make `figure.facecolor: white` the default for every backend anyway, which does generally look more modern.\n\nIt does mean it IPython ever changes their style to something on a non-white background things may not look as nice, but we'll cross that when we get there.\n\nCc: @pelson\n","author":{"url":"https://github.com/mdboom","@type":"Person","name":"mdboom"},"datePublished":"2015-11-06T14:53:25.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/5419/matplotlib/issues/5419"}
