You have been subscribed to a public bug: 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.
