[FieldTrip] ft_multiplotTFR.m crashing Linux machine

Hi David,

I also had similar problems, such as crashing of the VNC window on a
remote server.
I agree with Roemer that it's probably due to buggy opengl drivers.
More information at:

Briefly, you can run as first command:
>> opengl software

to force matlab to use the (less buggy) software implementation of opengl.

Then the trick "figure('renderer','zbuffer')" should not be necessary.
Hope this helps.
