title: OpenGL debugger / error tracer for OS X 10.7 (Lion)?
body: <p>What tool can I use best for tracing OpenGL errors? I once used gDEBugger, but that is not yet available for 10.7, and I used to have some problems with it. Xcode Instruments does seem to only have some driver statistics. All I need is a tracer that tells me which OpenGL call led to an error.</p>
