It looks like it's a known bug and is fixed in later versions.

My first guess is to agree with you that this is the root of the
problem.  Given that you're running over SSH with X forwarding, I
thought that may also be a factor.  However, a bit of googling for the
error message and it looks like it has come up a few times in relation
to GNU Radio tools.

I found a couple of suggested solutions:
1) apt-get install python-opengl
I don't really know what this issue has to do with python opengl
support, but there are a few people reporting that this fixed their
issue. I recommend trying this one.

2) downgrade to 2.8.x
I don't recommend this one at all.

I haven't tried either of these, but I am running WX 3.0 and I can
confirm that my tool osmocom_fft works as expected.
