Hello,
The loop below is at the end of OSGWIndow.cpp (around line 1650), and runs
infintely if there is no context. In that case, GL_INVALID_OPERATION is
returned all the time, and the loop never exits.
This happens if a PassiveWindow is destroyed while there is no current
active context.
Maybe, in PassiveWindow, one should call wgl/glx GetCurrentContext, thus
allowing hasContext() to return false? (Or check if you get the same error
twice in a row, but that's fixing the symptom, not the cause...)
if(testGLErrors && this->hasContext() == true)
{
GLenum glerr;
while((glerr = glGetError()) != GL_NO_ERROR)
{
FWARNING(("Window::frameExit: Caught stray OpenGL "
"error %s (%#x).\n",
gluErrorString(glerr),
glerr));
#ifndef OSG_DEBUG
FWARNING(("Rerun with debug-libraries to get more accurate "
"information.\n"));
#endif
}
}
Best Regards,
/Marcus
