I'd like to give it another day or so of testing to make sure, but it seems like the flicker on the internal screen is gone. I'm presently using this system docked ("Ultra" dock with internal DP hub) with multiple external DP & HDMI monitors, and the internal screen disabled, and I'm not seeing any issues on the external screens like Dmitry has. I'll give it a try with the internal display enabled to see if I hit the same thing. I would imagine the corrupted display on external monitor is probably unrelated to this eDP PSR issue, though.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
