I just submitted a patch to Mesa that fixes the issue with GL_BGRA that
remained, and makes the piglit test
"spec@ext_texture_format_bgra@api-errors" pass:

I agree we must have a piglit test for this to avoid regressions in the future.
I will provide one ASAP.

--- Comment #17 from Eduardo Lima Mitev  ---
I just sent for review a piglit test that checks that the combination of
internalFormat=GL_BGRA_EXT, format=GL_BGRA_EXT and type=GL_UNSIGNED_BYTE is
valid on TexImageXD and TexSubImageXD, as specified by the extension
:

http://lists.freedesktop.org/archives/piglit/2015-October/017535.html

This should prevent this regression in the future.

However, this test doesn't pass on master because current handling of GL_BGRA
format allows for this invalid combination (which is checked in the test):

internalFormat=GL_RGBA format=GL_BGRA_EXT and type=GL_UNSIGNED_BYTE

or

internalFormat=GL_BGRA_EXT format=GL_RGBA and type=GL_UNSIGNED_BYTE

So I also sent a patch to mesa-dev that improves this and make the test pass:

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.

Created attachment 118744
  --> https://bugs.freedesktop.org/attachment.cgi?id=118744=edit
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.

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_BGRA
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_XRGB and WL_SHM_FORMAT_ARGB layouts, so we can avoid a
conversion.

Spotted this report after bisecting :(

So, I can confirm the same behaviour under kde5/gentoo/qt-5.4.2: black windows,
and the commit that cause the problem seems to be

Sounds about right according to ilia's glxinfo list

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?

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.

https://bugs.freedesktop.org/show_bug.cgi?id=92265

Bug ID: 92265
   Summary: Black windows in weston after update mesa to 11.0.2-1
   Product: Mesa
   Version: unspecified
  Hardware: All
OS: Linux (All)
Status: NEW
  Severity: critical
  Priority: medium
 Component: EGL/Wayland
  Assignee: wayland-b...@lists.freedesktop.org
  Reporter: cale...@techgroup.me
QA Contact: mesa-dev@lists.freedesktop.org

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:
http://mesa3d.sourceforge.net/relnotes/11.0.2.html
> i965: Respect stride and subreg_offset for ATTR registers
