I tried stock 16.04, and upstream xorg; no improvement. What I've identified is: any xorg version that supports DRI3 shows a performance regression even if only DRI2 is active. Enabling DRI3 worsens video performance and tearing.
xorg-lts-vivid is the latest version that will work flawlessly. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1610591 Title: Video acceleration regression for Radeon Xpress 200M (r300) in xorg- lts-xenial & xorg-lts-wily To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1610591/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
