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 <https://www.khronos.org/registry/gles/extensions/EXT/EXT_texture_format_BGRA8888.txt>:
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: http://lists.freedesktop.org/archives/mesa-dev/2015-October/097211.html -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1504387 Title: [regression] Software client windows appear all-black on wily desktop Status in Mesa: Confirmed Status in Mir: Invalid Status in mesa package in Ubuntu: Fix Released Bug description: [regression] Software client windows appear all-black, as of today on wily desktop.
