I built the 4.8.6 kernel this morning and do not have the same flickering problem as I had 4.8.7 onward. I did notice a very big jump in GPU performance though from 4.7.0 to 4.8.6 (around 35-40% improvement on OpenGL benchmark) on the MacBook Pro 11,5 with the radeon driver. I did find that the GPU fan was full speed on initial first boot on 4.8.6+, noticeably very noisy but quietened down after some time. While I'm not experiencing any flickering on 4.8.6, I have noticed some subtle screen tearing on Gnome Shell transitions; such as when you hit the super key. In the past with the fglrx driver, there was an option to enable in the ATI/AMD configuration manager to address this tearing. I just noticed this tearing as I was looking for the flickering that this bug mentions.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
