Now on to my specific problem. I'm using the GD
> backend on Windows with Matplotlib 0.41.
First things first -- I haven't succeeded in getting the gd backend
compiled on windows. If you have some expertise here and are willing
to share, or better yet build a gdmodule and gd installer that I can
put on the website, I would be very much obliged! I contacted the
gdmodule maintainer some time ago over this issue and he had never
built it on windows either. In my googling, I discovered the perl gd
module for windows and following their lead, succeeded in building gd
lib, but ran into some troubles (can't remember what) building
gdmodule.

Now on to your problem. Is there a typo here? You say over 60 is
empty and under 65 is ok ?? Can you send me a script which replicates
the problem, with the two calls to savefig, one which has the problem
and which does not. Then I can begin to diagnose the problem; see if
it occurs under linux, see if it's a gd problem, see if it's a problem
on my end, etc....
Are you using matplotlib + GD for a web app server?
