I can confirm that the bug happens erratically for me as well. I see it when the monitor comes out of standby. I have never seen the problem on boot or on resume from suspend. As I've mentioned above, it takes 2 to 3 days with the most recent kernels for the bug to occur. My sense is that this was happening more regularly with 4.13 but I have no controlled, quantified data on that. If I could induce the bug reliably, it would be possible to bisect the kernel from 4.12 to 4.13 to pinpoint the issue. But this is almost prohibitively time consuming if I have to wait a day or two between each build. I can live with the problem but it sure is annoying.</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> <li>You are the assignee for the bug.</li> </ul> </body> </html>
