OpenGL not working in plugins on OS X 10.8 or below

We’ve come across an issue with older Mac OS’s where OpenGL drawing only works when a single plugin instance is open. Multiple instances of the same plugin (or our other plugins) cause some pretty wild drawing artifacts in the OpenGL only — almost as if they’re competing for the same context.

We’re not doing any shared memory stuff, and we’re on a fairly recent version of JUCE. Any help or info appreciated.

OK thanks. We will look into this.

Any new info here?

Bump. It’s hard to imagine that we’re the only ones trying to use OpenGL in plugins on OS X 10.8. Is anyone else seeing this?
