I've previously tried disabling hyperz on Tahiti with no luck in side stepping this bug, so I don't think this is the issue. Could there be other buffers that need similar treatment that are being ignored? Is there an easy way to test this locally?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
