I tested it by setting the inactive bit in the same register along with the enable bit, this case did not trigger flickers. So, it looks like the MST case needs to be handled differently.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
