I've discovered that I'm affected by this bug, but *only* when I've got 2 chrome windows open on different desktops (I've got a 2x2 grid of desktops) on Ubuntu 16.10 - it wasn't doing this on Ubuntu 16.04. How can this be a duplicate of a webkit bug when chrome doesn't even use webkit though? uname -a: Linux Riikaan 4.8.0-39-generic #42-Ubuntu SMP Mon Feb 20 11:47:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux glxinfo: name of display: :0 display: :0 screen: 0 direct rendering: Yes Extended renderer info (GLX_MESA_query_renderer): Vendor: Intel Open Source Technology Center (0x8086) Device: Mesa DRI Intel(R) Kabylake GT2 (0x5916) Version: 12.0.6 Accelerated: yes Video memory: 3072MB Unified memory: yes Preferred profile: core (0x1) Max core profile version: 4.3 Max compat profile version: 3.0 Max GLES1 profile version: 1.1 Max GLES[23] profile version: 3.1 OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Kabylake GT2 OpenGL core profile version string: 4.3 (Core Profile) Mesa 12.0.6 OpenGL core profile shading language version string: 4.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL version string: 3.0 Mesa 12.0.6 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL ES profile version string: OpenGL ES 3.1 Mesa 12.0.6 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10 More information available on request. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1628866 Title: After upgrading to 16.10, Chrome has become unusable because of extremely slow update Status in X.Org X server: Unknown Status in xorg package in Ubuntu: Confirmed Bug description: Both Chrome and Firefox actually were extremely slow regarding visual update (1 second after clicking a tab, lagging when entering text). Examining this old report: https://bugs.launchpad.net/ubuntu- gnome/+bug/1386721, I tried disbling bootloader graphics and VESA framebuffer, which suddenly made firefox behave as it used to, but chrome shows no improvement.
