Re: [matplotlib-devel] SpanSelector with gtk3cairo backend

[Thomas C. <tca...@gm...>]

Not sure what you mean about agg + py3k, it should work fine (as we test
it).

The issue is that the cairo backend is a vector backend, which does not
have a notion of blitting, which is something that span selector uses to
make it nice and snappy.  Should be able to get it to work by passing the
kwarg `useblit=False` to the constructor.
