            Bug ID: 91604
           Summary: Graphics corruption on resume from suspend - 2015
                    ThinkPad models and more
           Product: xorg
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/intel
          Assignee: chris at chris-wilson.co.uk

        QA Contact: intel-gfx-bugs at lists.freedesktop.org

On resuming from one of the 2015 ThinkPad models, there is terrible graphics
corruption. Text gets garbled, the performance is poor, etc. There is a bug
opened in Launchpad for this issue:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1452318
but thought I'd open one in the intel component here. 

There is a workaround that if you change graphics acceleration from SNA to UXA,
everything works but comes with super slow graphics performance. Please let me
know if there is any other information I can provide.
