I just opened Chromium and shortly after it opened, the bottom half of the screen glitched for a split second. Also, when I am typing these comments on Bugzilla, sometimes the word I am typing disappears for a split second. > Thanks so much for testing, also could you share the dmesg right after ones > of those glitches happens? There is nothing in dmesg when the glitches occur. Also, I have noticed that even with PSR2 disabled, I still see some rare glitches with only PSR1 enabled on both of my laptops. For example, I wake my XPS 13 from suspend, the image on the screen shakes briefly. Also, when I am using Chromium, part of the screen flickers sometimes. These issues don't happen when PSR is disabled completely.</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>
