Dear Chris,
You may be right about the culprit being Mesa OpenGL.
I usually run IDL from emacs (or the command line) rather than from the Workbench, and so have
not fiddled with the settings for the graphics backend. I just fired up the IDL 8.3 Workbench and
tried to run my example script. It worked as usual with software rendering enabled, but not
at all with hardware rendering enabled, instead emitting error messages such as
% Graphics device not available: GL_COCOA.
% Attempt to destroy an object within its INIT method: <ObjHeapVar11153(GRAPHICSWIN)>.
% Execution halted at: $MAIN$
So, hardware rendering appears not to work at all(!).
I'm running IDL 8.3 under OS X 10.9.4 on a Macbook Pro.
All the best,
David
