That seems to hit an assert in my debug build. Hmm, seems like you're right. Once I flag the bit it works. However, that bit isn't flagged as supported in either linearly or optimally tiled images (of multiplane format). Should this be flagged as supported? It seems like it works.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
