I am indeed not using VBOs, so the deferred calling is plausible I suppose. The curious thing here is that the reference implementation application uses the exact same function calls in the same order and they display normally in apitrace. Wouldn't a driver bug cause this application to also fail

Hi, I'm working on a project using opengl on linux, and I turned to apitrace for debugging when I encountered a problem. According to apitrace, it seems that calls to glTexCoordPointer and glVertexPointer are "not happening"; they do not show up in the trace dumps anywhere. Using gdb, however, I
