Lots of video tearing that did not occur when using xserver-xorg-video-radeon-lts-vivid. System is an older Pentium laptop (Packard Bell EasyNote) with a Radeon Xpress 200M chip (r300 driver). Video acceleration was working with DRI2 under the Vivid stack (kernel 3.19-64-lowlatency + xserver-xorg-video-radeon-lts-vivid). I also tried upgrading to the Wily kernel (4.2.0-lowlatency), and video acceleration works fine with the Vivid xorg. I reported this in launchpad previously, and it was dismissed as "invalid" since Wily is EOL. The problem, however, persists in the Xenial stack, so I'm reporting it here. Attached are the respective Xorg.0 logs.
