Sorry for the delay ; the problem has been happening for at least 2 months, but it took me ages to qualify it, and find it here on this bugtracker. Flickering happens every now and then (between one minute and 1-2 hour after having opened my graphical session). I can barely stop it by moving a lot my mouse cursor (screen stops flickering until i stop moving the cursor, where flickering happens again immediately). Flickering is resolved more durably by suspending the machine: on resume, I can work again until next flickering sequence (idem, between 1 minute and some hours). I'm currently testing the "i915.enable_psr=0" workaround to see if the bug occurs again. I will report here. Feel free to ask me about any missing information.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
