Upgrade to chromium-58 (masked) make video playback, such as html5 on youtube flickering, slowed down or tearing or hanging (while sound is working). Rebuilding chromium with built-in ffmpeg and libvpx (disable of system-ffmpeg and system-libvpx) does not change a behavior. I use laptop with Atom CPU and built-in intel graphics. Drivers: xf86-video-intel-2.99.917_p20170216 USE="dri dri3 sna udev -debug -uxa -xvmc" Xorg: x11-base/xorg-server-1.19.1:0/1.19.1 USE="glamor ipv6 suid udev xorg -debug -dmx -doc -kdrive -libressl -minimal (-selinux) -static-libs (-systemd) -tslib -unwind -wayland -xephyr -xnest -xvfb" Chromium: any version from 58: chromium-58.0.3013.3 chromium-58.0.3018.3 Downgrading to chromium-57.0.2987.54, which is built with default USE flags completely resolves the problem. Reproducible: Always
I'm not having any problems here. If other people are having video playback issues, please share your data and maybe we can find a pattern.

Also consider downloading and building the sources and bisecting.

For me videos are not playing at all (except sound), with chromium-58.0.3029.6. Chromium-57 worked fine. I can make them play again, if I disable hardware acceleration. This is compiled with clang, kernel 4.10.1, xorg-server-1.18.4, libdrm-2.4.75 with Intel video (Kaby Lake).
Found the issue I am having in the chromium bugtracker: https://bugs.chromium.org/p/chromium/issues/detail?id=698596 If you believe the latest comments there, the problem is fixed with version 58.0.3029.19. Unfortunately I did not succeed to compile 58.0.3029.19 with clang-4.0.0 or gcc-6.3.0.
