Thanks for the report, @zmo. 

Jiawei, could you take a look at these failures in Windows?

For the record, this is not the update to date driver (which has a large regression).  This is the older but more stable driver

OK. I will investigate them.
Are you using 15.40-4501 driver? The situation is very similar to that.

Thanks for the update Jiawei. This is good news. Hoping that we can avoid these kinds of regressions in the future by running the WebGL 2.0 conformance tests before shipping the drivers.

Thank you for the update.  This is good news.

Jiawei: the bots updated their drivers. Can you update the test expectations accordingly?

Got it.

Hi all,

New Intel D3D driver 15.46.4729 for SKL/KBL has been released:
https://downloadcenter.intel.com/download/26941/Graphics-Intel-Graphics-Driver-for-Windows-15-46-?product=80939

We verified the following cases mentioned in this report are fixed with this driver:
deqp/functional/gles3/framebufferblit/default_framebuffer_03.html

deqp/functional/gles3/framebufferblit/default_framebuffer_06.html

deqp/functional/gles3/fboinvalidate/format_01.html
deqp/functional/gles3/fboinvalidate/format_02.html
conformance2/textures/misc/angle-stuck-depth-textures.html

We have also verified 15.46.4729 has no regressions in WebGL CTS.

This is great!

Ken, should we update our Win Intel bots' drivers?

Yes, certainly! Filed Issue 748248. Thanks Jiawei and the Intel D3D driver team for these fixes!

Hi kbr,
I'm sorry that we found the GPU process may fail to create when we use use-gl=desktop on Windows with this new driver. We are now investigating this, so please don't upgrade the bot now. 

Thanks Jiawei for the heads up. While we'll appreciate your investigating this, that configuration is unsupported (and untested on our bots) so it wouldn't be a blocker. However, if --use-angle=gl is broken, that would be a significant problem. Does that work?

Unfortunately this new driver doesn't work with --use-angle=gl either and cannot run angle_end2end_tests when using OpenGL back-ends.

We are investigating this significant problem and trying to find the root cause. 

Thanks for the heads up Jiawei. We'll try to abort our upgrade and will appreciate your help in the future to ensure regressions like these don't make their way into the drivers.

Hi all,

New Intel D3D driver 15.47.4815 for SKL/KBL has been released:
https://downloadcenter.intel.com/download/27199/Graphics-Intel-Graphics-Driver-for-Windows-15-47-?product=80939

The following test has been fixed on both HD530 and HD630 with this new driver:
conformance2/textures/misc/angle-stuck-depth-textures.html

Thanks Jiawei. Requesting upgrade of this bot:
https://ci.chromium.org/buildbot/chromium.gpu.fyi/Win10%20Release%20%28Intel%20HD%20630%29/?limit=200

in Issue 777033.

Changing Summary since we don't have an Intel HD 530 bot on our waterfall any more.

Driver's been updated starting with this build:
https://ci.chromium.org/buildbot/chromium.gpu.fyi/Win10%20Release%20%28Intel%20HD%20630%29/854

If it looks reliably green then let's try removing the suppression for this test. Thanks.
