Hi Clare,
Which backend are you using, and can you show an example script?
The blitting functions are a bit unusual as they try to draw stuff to the
figure outside of the event loop. This is e.g. causing problems with
animations, which makes use of the blitting functions. We have been looking at
that recently (see https://github.com/matplotlib/matplotlib/issues/531) but we
haven't come up with a solution yet. Solving this issue may also fix your
problem (which sounds like an event loop problem), so you may want to follow
issue 531.
Best,
-Michiel.

Hi,
To improve plotting speed, I decided to use blitting(canvas.copy_from_bbox(),
canvas.restore_region() & canvas.blit()) instead of canvas.draw(), however
panning & zooming stops working after this change. Now, when I click on the
'Pan/Zoom' button or the 'Zoom to rectangle' button on the Navigation Toolbar,
my plot becomes empty. I don't know what's going wrong, can someone please
point me in the right direction?
Thank you,
Clare.
