This patch, by itself, significantly reduces but does not eliminate the occasional black 'flicker'. At this point, the rate is reduced sufficiently that the system's actually usable - I maybe see one or two flickers over about half an hour of typical usage, rather than several per minute. Using i915.enable_psr=0 still makes them go away completely.</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>
