In my experience you must read the pixels in the thread which created the context, although I'm there may be a way around that.

Do you get any error messages, exceptions? have you called check on the context to see if there are any OpenGL errors?

Try turning debugging on for the contect - it's a static boolean, it'll give you more info on what's going on that way.

Hope this is of some help.
