Full CPU with GTKAgg when displaying a figure.

Development matplotlib-devel

Hi All,

I don't have time at the moment to submit a ticket, but I thought I'd see if anyone else is having this problem:

With latest master on 1.5-devel using GTKAgg backend, (and in ipython 3.0.0-dev, python 2.7.8, MacOSX 10.9.5) if I do figure() and nothing else, and then run 'top', I see Python running 100% CPU for the process. Closing the figure stops Python hogging the CPU.

With latest 1.4.x, I do not see it.

Yes, this was discovered recently in connection to changes in how idle events were handled. I don’t recall if there was an issue created for it, though.

Not sure why my message didn’t go through earlier, but yes, the
issue already exists in the system, see
