    Access violation from ig9icd32.dll

      Hi,

      One of our customers is using a Surface Book, he began experiencing problems with our CAD software once he received update with 22.20.16.4811 driver for his Intel HD 520 graphics adapter. He had no problems with previous version of 20.19.15.4463.

      Our investigation shows access violation from ig9icd32.dll when we call wglSwapLayerBuffers.

      We solved the problem by downgrading his driver, but this is not a permanent solution and it would be a lot better if next driver version won't have this bug.
