(EDIT :got the model name names wrong before)
its works fine on the 3000 with openGL and with the HD Graphics 4000 with directX ,and Mac-mini
with the 4000 we needed to add
WGL_FRAMEBUFFER_SRGB_CAPABLE_ARB
to wglChoosePixelFormatEXT in order to get corect sRGB rendering,
on older HW only calling glEnabe with GL_FRAMEBUFFER_SRGB got the correct frame buffer sRGB behavior .
the 4500 seems to respect GL_FRAMEBUFFER_SRGB only for pixels formats with WGL_FRAMEBUFFER_SRGB_CAPABLE_ARB, as needed by the opengl spec, but it seems to break MSAA.
there no pixel format with WGL_FRAMEBUFFER_SRGB_CAPABLE_ARB and WGL_SAMPLE_BUFFERS_ARB for HD Graphics 4000
we are using the latest drivers (Dec 2014)
is that a bug, or there a work arounds?
tnx

Hi,
Based on your description it sounds like it could be a driver issue. You should not have to add WGL_FRAMEBUFFER_SRGB_CAPABLE_ARB with HD4000. I need to double check on that though. I am moving your post to the Graphics Driver Bug Reporting forum. If you look at the How to report suspected graphics driver issues sticky post you will see a format to report issues in. If you do that for me I can get an internal ticket filed. this will help as I discuss this issue with our OpenGl driver developer team.
Thanks!
