           Summary: Cursor corruption on every 255th horizontal pixel
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/radeonhd
        AssignedTo: lverhaegen@suse.de
        ReportedBy: fry.kun@gmail.com

Xorg.0.log

Cursor corruption appears when the cursor is on particular parts of the screen.
The corruption appears as blinking lines next to, or on top of the cursor.
These distortions don't change in patter if the cursor is moved strictly up and
down (same horizontal pixel), but change if the cursor is moved to left or
right, even by 1 pixel. The affected areas of the screen are columns ~10px wide
around every 255px (x % 255 == 0, but not x === 0).
The corruption seems to be limited to the cursor only - it doesn't stay around
when the cursor is moved away, and doesn't appear on screenshots.
Different cursors (arrow, text selection, etc) seem to be all affected by the
problem.

lspci output:
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility X1400

hardware is Dell laptop, model Inspiron e1505

driver ver. (commit) a9af866ae712a0048d374dc640e482d1f4ce8859

The problem was first noticed around Dec '07, but I have not tried any versions
since (IOW, I don't know if the problem has been fixed since, but came back --
or if it hasn't been fixed yet)
