There's no provision in the spec to disallow someone feeding you a aligned-to-4 buffer with GL_RGBA32I format if you return "4" as the value. Oh, unless I totally misunderstood what you were saying, and that situation should work. In which case, apologies for the noise.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
