hm, hard to say what the underlying problem is as this is just a generic
check for OpenGL errors at the end of rendering, so the point of
interest would be where the OpenGL operation that causes this error.
Do you have access to an OpenGL Debugger that you can run the program
through to pinpoint the error location?
Does the program crash or do you only get a blank screen? If the former
can you try to get a backtrace of the crash location, perhaps that gives
a hint too?
Thanks,
Carsten
PS: Sorry, I've not had a chance to look at the description of your
program's sync behaviour, planning to do that later today though.
