Description:
After update mesa from 11.0.1-1 to 11.0.2-1 in Weston (launched from the console or 'X') all the windows black (see screenshot: https://i.imgur.com/Oe5X0en.png). After downgrading mesa package weston work fine.

Additional info:
* Problem mesa version: 11.0.2-1
* Weston 1.9
* Weston running from the 'X': http://pastebin.com/jksF4DT4
* ArchLinux
* Intel I4700HQ + Intel Graphics HD 4600 + NVIDIA 850m

Assumption:
I think that to blame the following correction in mesa:

> i965: Respect stride and subreg_offset for ATTR registers

My mesa snapshot happened to have the commit mentioned above, but weston
was okay. Updated mesa to current HEAD, and the problem described
happened.

Reverting 5edd996 (mesa: Use the effective internal format instead for
validation) helps, so it should be the problematic commit.

There appear to be two potential problems here.  One is that Weston
tries to use GL_EXT_abgr in ES even though it is not an ES extension.
The second is that mesa advertises it and then falls over when you try
to use it.  If we weren't advertising it, Weston would fall back to
other paths and be OK.  I see two options:

 1) Actually support the extension even though it isn't technically an ES extension.
 2) Stop advertising it.

I'm going to hazard a guess and say that mesa is probably the only ES
driver to support GL_EXT_abgr.

Thoughts?

Sounds about right according to ilia's glxinfo list

So, I can confirm the same behaviour under kde5/gentoo/qt-5.4.2: black

I don't think you mean GL_EXT_abgr, I don't see Weston using that.

Weston is using GL_BGRA_EXT format, when GL_EXT_texture_format_BGRA8888
extension is available. Weston's GL-renderer refuses to start without
this extension.

I believe this is because GL_BGRA_EXT, GL_UNSIGNED_BYTE matches the
WL_SHM_FORMAT_XRGB8888 and WL_SHM_FORMAT_ARGB8888 layouts, so we can
avoid a conversion.

Stderr from running weston-launch

Also hitting something like this, black screen on weston-launch.  I
believe this may be the same thing?  Attaching stderr output for
verification.  I'm running on Centos 7, same versions of weston and mesa
I can build an older version of mesa if necessary to test.

I'm currently on holidays and away from my dev laptop until next
Tuesday. I will tell somebody from my team to keep an eye on this.

I took a quick look at Jason patch and it looks good. Thought I would
have preferred to avoid adding the check for GL_BGRA_EXT inside the
block that resolves the effective internal format. I wish there was a
way to do the same either inside _mesa_base_tex_format() or later down
in _mesa_es3_error_check_format_and_type. But I would need more time to
think on another way. So I would go ahead with that patch now.

Since I cannot test it here, I would let somebody else review it (if it
is not done already).

Sorry for the regression and the bad timing with me on holidays.

No piglit, dEQP, or CTS tests indicated this regression.  However, a
major consumer of Mesa was debilitated due to this bug.

This bug cannot be marked fixed until there exists a piglit test which
prevents future regressions of this type.
