            Bug ID: 88739
           Summary: GPU crash - segfault at error in chrome
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: vstadnichenko at gmail.com
        QA Contact: intel-gfx-bugs at lists.freedesktop.org

It looks like when I open a page that contains video content in Google Chrome,
the page stops responding, then the cursor becomes stalled and stays at that
location, while the mouse keeps working moving the focus point instead of the
cursor. The focus point highlights the items it's pointing to, and the mouse
operates normally while the cursor is lost behind.

If I log off, the login page is corrupted - it's 2-3 inches horizontally offset
to the side.
