Intel has released a new graphics driver for Iris and HD Graphics GPUs (Haswell and Broadwell processors). Compared to v4170, this new version 4206 brings some OpenGL bugfixes (GLSL), including the ones related to MadShaders 0.4.x:

A thread dedicated to Intel drivers/GPUs is available HERE with screenshots of GLSL Hacker based demos and apps that have rendering issues.

You can download Intel v4206 from THIS PAGE.
A thread to post feedback is available on Intel’s forums HERE.

v4206 is an OpenGL 4.3 driver and exposes the same OpenGL extensions than v4170 and v4080.

Thanks for the “dolphin” demo fix for Intel and the inclusion of “Am I dreaming” demo.
It’s been there from the beginning but never worked.

I see that you ‘ve noticed my posts at Intel forums.
They finally fixed all the bugs, but one.
There are artifacts while playing the “Am I dreaming” demo, as I posted to Intel forums.

One more interesting thing:
Nvidia drivers/ cards have usually problems with “flaring” demo.
Depending on the driver version, sometimes it’s fixed sometime is not and you see a very disrupted image.
The most interesting fact is that when the demo runs OK on an Nvidia card, the output of the rendering is different than the output of Intel ! (and I think AMD too)

Which one is right ?

Using a Radeon 5750 card with Win 8.1 Pro x64 and latest WHQL 14.12 drivers I had problems with various demos:
