An option to turn it off would be nice in that case.\n### SourceForge Comments\n#### On Thu Sep  6 16:07:54 2007, mdboom wrote:\n\nLogged In: YES \nuser_id=119312\nOriginator: NO\n\nIt appears that the text is re-rendered to a newly allocated buffer each time the text is drawn.  Perhaps some caching of text elements would help.\n\n(Mostly just making a note of it for someone else to work this through, or until I have the time.)\n### SourceForge History\n- On Wed Mar 21 08:03:30 2007, by yohell: File Added: 221568: test.py\n","author":{"url":"https://github.com/ddale","@type":"Person","name":"ddale"},"datePublished":"2011-06-20T21:19:13.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/347/matplotlib/issues/347"}
