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.

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?

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.

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.

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.
