One thing I found during troubleshooting - for my hardware at least the fix in #8:
Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "sna" Option "TearFree" "true" Option "DRI" "3" EndSection For me adding the Option "DRI" "3 line caused Chrome to begin locking up when right clicking on pages (the menu would begin to display then Chrome would freeze requiring it to be killed - I think it was also causing issues with Xorg / Unity as the desktop itself would not be responsive at the time. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1586539 Title: Major screen flickering in Chromium and Google Chrome Status in X.Org X server: Unknown Status in xserver-xorg-video-intel package in Ubuntu: Incomplete Bug description: On a fresh installation of Ubuntu 16.04 I noticed major screen flickering issues in Chromium and Google Chrome browsers. Since this never happened in Ubuntu 15.10 with exactly the same Google Chrome binary, I believe, bug is caused by something that was added/updated in 16.04. I came across some discussions where different people suggested that it is related to new X.Org version. Here's a video to show what is happening: https://youtu.be/l21WsKz3fZc?t=45s I could fix this flickering with --disable-gpu-compositing switch, but this slows down page drawing significantly so it can't be considered a workaround. There is also a Chromium bug report: https://bugs.chromium.org/p/chromium/issues/detail?id=606152, but I don't think they will fix an Ubuntu-specific bug. Update: this indeed happens only when browser window is maximized. WORKAROUND: 1. sudo apt-get purge xserver-xorg-video-intel 2. sudo rm /usr/share/X11/xorg.conf.d/20-intel.conf (for those who created this file before) 3. reboot ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xorg 1:7.7+13ubuntu3 Uname: Linux 4.6.0-040600-generic x86_64 .tmp.unity_support_test.0: ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 BootLog: CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Sat May 28 00:01:20 2016 DistUpgraded: Fresh install DistroCodename: xenial DistroVariant: ubuntu DkmsStatus: vboxhost, 5.0.20, 4.4.0-22-generic, x86_64: installed vboxhost, 5.0.20, 4.6.0-040600-generic, x86_64: installed EcryptfsInUse: Yes ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a2e] (rev 09) (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.
