[vtkusers] Error during cleanup: wglMakeCurrent failed in Clean()

Thu Nov 26 06:34:40 EST 2009

Dear All,

A few months ago I experienced similar problems. My application was
crashing or causing heap corruptions when closing the vtkRenderWindow
on my pc at work. On my Netbook it could even result in a BSOD and an
immediate reboot. At home with NVidia hardware everything worked fine.

I finally traced the bug up to "ig4icd32.dll: OpenGL(R) Driver for
Intel(R) Graphics Accelerator.": somewhere around the SetPixelFormat()
method. From there on, debugging became a lot more difficult and I
decided to upgrade my Intel driver to version 6.14.10.5047.

Regards,
André
