Possible memory leak in graphics drivers when creating OpenGL windows

idata — Fri, 28 Dec 2012 04:47:55 GMT

Hello, I am a software developer and I have noticed an issue when using the Win32 API to create OpenGL windows. The issue only exists when using a computer with Intel HD 4000 graphics. (I am using the latest driver, 9.17.10.2875). The issue does not exist when I run the same exact code on other computers with either NVidia or AMD graphics, so I believe it to be an Intel driver issue.

When I create a Win32 window with an OpenGL context, my memory usage grows, as expected. However, when I destroy the window, the memory usage does not go back down.

Since my application can create or destroy many windows, the memory usage eventually gets very large (over 1 GB), due solely to creating and destroying OpenGL windows, and not doing anything else.

Has anyone else experienced this? I can privately share software with anyone who would like to test this.

Thanks,

Eric

Hello,

Let me forward this to our escalation point and see what would be the proper path to check on this issue.

Hi Eric

Could you please test again with the latest Intel HD Graphics driver version 9.17.10.2932?

Hello,

I'm facing the same issue with this card (except it's with JOGL). The links given above are not working. My current driver version is 8.15.10.2696, the one propose seems more recent but I cannot find a working link to it.

Did you finally find a solution?
