Exception occurs when window opens via OpenGL(OpenTK)

[MYosh8]

Dear sirs,

Please find below issue report.

[Description]

   Exception occurs when window opens via OpenGL(OpenTK) application.

   It occurs always when the graphic driver version is "25.20.100.6323".

   The exception never occured by using the former version.

   We suppose that similar phenomenon shold occures other Apps.

   We hope the issue will be fixed at later version ASAP.

[Steps to reproduce the issue/bug:]

   1. Open the new window via OpenGL(OpenTK).

      We provide the exception log Windows output.

​Hello WaanerG_Intel,

Thank you for your answering.

I will downgrade the version which can work properly with OpenTK.
