Can you give some more details? I don't understand where you're trying to draw the string using [NSString drawInRect:withAttributes:]. Is this in a custom parameter, or as part of rendering? When using a pBuffer, does glGetError() return anything? Have you tried running with OpenGL Profiler? Darrin On Jul 7, 2012, at 9:40 AM, Christoph Vonrhein wrote:

Hello Darrin (and everybody else),

I am trying to draw some text on the screen in a FxPlug plugin with the [NSString drawInRect: withAttributes] method. In continuously wind up with lots of "invalid context 0x0" error messages in the console.

This also happens when I try to draw text to a pBuffer.

Any ideas?
