           Summary: 2D acceleration on i815 unusable
           Product: xorg
           Version: 6.8.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Driver/i810
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: freedesktop.org at waymouth.org


I've just migrated from XFree86 4.3.0 to X.org 6.8.0 to see how things look. 
While 2D acceleration worked perfectly in XFree86, it's horribly broken in
X.org.  My initial XDM screen looks horribly corrupted, with only a vague
outline of the login box visible.  After logging in, some things seem to be OK,
but other areas of the screen are corrupted.  It seems like areas involving
direct pixel plotting by an application work, whereas line-drawing and such
fail.  Scrolling in firefox is broken, only some parts of the browser update. 
All in all, pretty much nothing works right, and, of course, when I turn off
acceleration, everything is slow as hell.  This seems to be independent of
bit-depth.
