           Summary: Cursor corruption with R100 and latest git in Fedora 10
           Product: xorg
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: rankincj at googlemail.com
         QAContact: xorg-team at lists.x.org


I have just tried the latest git build of xf86-drv-ati and the cursor is not
being rendered in the correct place on the screen. (There is a rectangle of
corruption where the cursor hotspot is.)

The latest commit that works is:

commit 1429133ffdbfe046249fcaaa4cbee432a1012e55
Author: Michel Dänzer <daenzer at vmware.com>
Date:   Mon May 18 17:59:00 2009 +0200

    EXA: Set new EXA_SUPPORTS_OFFSCREEN_OVERLAPS flag when we have a 2D engine.

so it's probably this commit which is the culprit:

commit 88a9e98341d96e5e7f48b69aed597d1bada6313a

    Pre-atom: Improve engine clock setup code

    Also remove SetMemoryClk() for pre-atom cards for now
    as it requires quite a bit more asic specific work.
    To set the mclk we'll need to use the mem reset/dll tables
    in the bios.

This is my graphics card:
