Would you be able to narrow which package precisely caused the regression based on the date when it started to occur? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1547800 Title: gpu stuck on render ring Status in xserver-xorg-video-intel package in Ubuntu: Incomplete Bug description: Happens with or without chromium hardware acceleration.
