suppressing run time openGL warning

[nuun]

I am periodically getting the following warning while running a c++ console application.

Code: Select all

OpenGL Warning: GetRandomRgn returned (-1) instead of (1), VisibleRegions update failed

First, can anyone verify that the warning is indeed generated by VirtualBox, not my application? If so, since this failed call seems to have no adverse effect, I will be satisfied with simply suppressing the warning. Is this possible?
Thanks,
