Missing function calls?

[Mike Blumenkrantz]

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 to display these function calls?
