           Summary: The ATI driver shipping with Ubuntu 7.10 incorrectly
                    handles drawing dotted XOR lines
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW

          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: smacfarl at gmail.com
         QAContact: xorg-team at lists.x.org


I have a Radeon 7000 card. I have the Ubuntu 7.10 installed.

Launch GIMP 2.4rc3 which ships with Ubuntu 7.10. The new GIMP uses XOR of  
dashed lines with a dash pattern consisting of a single 1-pixel segment, to
create a dashed box in the upper left corner of the cursor. This box appears
bright green by default and leaves little trails all over the client area on
mouse move events.

The GIMP people are not doing anything unusual with their graphics calls,
therefore the problem is with the driver on this specific hardware. See this   
GIMP bug report for details.

Also see this Ubuntu Forums bug report for a screen shot of the mouse trails.

The rest of the Ubuntu Forums thread talks about problems with the default ATI
driver configuration in Ubuntu more or less.
