Debugging OpenGL Frames

When debugging an OpenGL frame, the debug navigator shows the OpenGL call trace that generated the captured frame. The call trace includes the stack frame for each OpenGL call.

Note: The debug navigator shows content only after Xcode has captured an OpenGL frame.

The debug navigator contains the OpenGL call trace and a filter bar.

With the filter bar (the bottom box on the left in the screenshot) you specify the OpenGL calls and stack frames you want to see.

• Call filter: Shows only markers and OpenGL draw calls.
• Call stack slider: Shows stack frames, from only the most relevant to all of them.
