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: <a href="http://lists.freedesktop.org/archives/mesa-dev/2015-October/097211.html">http://lists.freedesktop.org/archives/mesa-dev/2015-October/097211.html</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
