            Bug ID: 97202
           Summary: IvyBridge broken fonts on resume
           Product: xorg
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/intel
          Assignee: chris at chris-wilson.co.uk

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

I have laptop with i7-3520M, Ubuntu 16.04 and latest oibaf mesa/drivers.

>From time to time (not always) when laptop comes back from sleep majority of
letters doesn't get rendered. All decorations and everything is and letters are
lost - so I see empty button frames, for example. In some cases some letters
may be visible immediately after resume but when I try to interact with this
particular window they disappear.

This doesn't happen all the time but is quite often and I also have another
laptop with Skylake CPU and similar software setup and I've never seen it
happening there.
