OpenGL related driver bug

MEnne — Fri, 31 Oct 2014 10:18:00 GMT

Hello,

I use OpenTK to develop an OpenGL based application for Windows. I use vertex buffer objects to upload vertex data. The problem is that the Intel driver graphics seems to have a bug because the OpenGL function: "GetBufferParameter" does not return the correct buffer size. I've already described my problem the OpenTK community, but they pointed me to this forum because they think its a driver bug.

The full problem can be found here: http://www.opentk.com/node/3823 GetBufferParameter behaves strangely | OpenTK

I use Windows 7 and have a http://www.intel.com/p/en_US/support/highlights/graphics/cp2-hd3000 Intel® HD Graphics 3000. Driver is 9.17.10.3517

Help would be really appreciated.

Enne, I am going to search for additional information on this behavior.

Are you getting the same behavior when using the previous Driver version 3347 https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23376 Intel® Download Center ? Please let me know.

Hello Sylvia,

I've tried it with 3347 now as you suggested and yes, the bug is also present in this version.
