Hello.
I remember, or seem to, that there was a tool long time ago that enabled to see what an opengl application was doing (sending to the api…), thus understand its bugs.
I don’t know if i’m clear or not, but i was not able to find that tool anymore.
Anyone has a pointer?
Hi !
The only one I know of is the trace tool they made for K3-D, have a look at their website, I think there should be an URL to it there somewhere.

thanks. what i was missing wasd the ‘trace’ word.
A quick search gave more results than using ‘debug’. 
here is the tool, in case it interests other people: http://www.hawksoft.com/gltrace/
