wglCreateContextAttribsARB crashes

In my application, it crashes when I try to create wglCreateContextAttribsARB for the 128th time. It is always the 128th time, I always pass the same arguments, and it always returns 0x2095(ERROR_INVALID_VERSION_ARB). I know that it is a valid version, due to the fact that it works the first 127 times.

Is there any reason for this function call failing at this specific number?

Solution

  • I'd bet on driver limitation, aka a bug.

    That said, ask yourself why you need so many calls to the context creation function. A typical application uses 1. Many applications use 1 per window. What are you trying to do that requires 128 contexts?
