Hi Christopher, Thanks for taking a look into this issue - I've completed some troubleshooting based on your suggestions and have some more information that I hope is useful.
I'm running a Chromebook using crouton to run Ubuntu in a chroot. 1. Unfortunately I'm not able to install anything other than a stable LTS on the hardware that exhibits the issue. 2. Removing the xserver-xorg-video-intel package and the conf file appears to have either resolved the issue or decreased it to the point where it is not currently noticeable. I've been running it for a day or so - will update if the issue occurs again. 3. Using UXA appeared to decrease the frequency of the issue similar to the above - however overall performance did suffer with rendering of pages slower, and I believe worse performance in Unity. 4. The issue has occurred across all the Chrome releases I've installed on this hardware (around the last two months) and occurs with the latest stable Chrome release as well. It was present with both xenial 16.04 and 16.04.1 releases. 5. It's an Acer Chromebook 11 - C730 6. Due to running on a Chromebook I'm not able to recompile the kernel - however the issue has occurred across multiple stable ChromeOS releases (from the last two months since this hardware has been running). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1653295 Title: Chromium and Chrome flickering Status in xorg package in Ubuntu: Incomplete Bug description: Chromium and Chrome 55.0.2883.87 flickering.
