IMO it is proof that glxgears does not suffer from the issue described, because 21 us cost for decorations is pretty much nothing. Attaching decorations to the Chrome window causes a significant slowdown, but is it only when playing video in Chrome? If the slowdown happened regardless of web page content, I might suspect a pixel format difference between the decorations and Chrome content.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
