Hello,

I have some trouble using glPolygonOffset on INTEL card. It doesn't seems to be taken in account.

System Setup Information:
-----------------------------------------

GPU: Optimus system with quadro K2100M - driver 10.18.13.6175 and Intel HD 4600 - drivers 10.18.14.4432 on a DELL precision M4800
Os: Windows 7 64
Proc: Intel Core I7-4930MX
API: OpenGL

Steps to Reproduce:
-------------------------------

- Unzip archive and execute polygonOffset.exe. Source code is included in archive. You may need vc2015 redist, included in archive.

Expected Results:
-------------------------------

offset_ok.png

Actual Results:
-------------------------------

offset_ko.png (Z fighting between teapot and wire teapot)

Additional Information:
-------------------------------

The issue occurs with INTEL but is not reproducible on various NVidia or AMD GPU. It has reported also on HD 5500 driver 20.19.15.4531

Hi Andrieu,

Hi Andrieu,

I'm afraid no further driver releases are planned for the 15.36 and 15.40 branches that support the HD 4xxx products.

It is on a limited basis, I am checking to see if/when the next driver release is planned.
