Since upgrading to matplotlib 2.0.0, whenever I start a matplotlib-enabled session (e.g., `ipython --matplotlib`) or a new window is created, it steals focus from the OS.  I'm using the `TkAgg` backend, though the same thing happens with Qt5.\r\n\r\nThis is particularly a problem for some test codes that create a large number of windows while running; I effectively cannot access the OS at all when the tests are running, even the terminal, so I can't kill the thread.\r\n\r\nAny suggestions on what might have happened with this latest upgrade?  Since this was anaconda-installed, I can't rule out a change in the backends rather than with matplotlib, but I think the relevant expertise is likelier to be here.","author":{"url":"https://github.com/keflavich","@type":"Person","name":"keflavich"},"datePublished":"2017-03-09T01:54:05.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":13},"url":"https://github.com/8246/matplotlib/issues/8246"}
