           Summary: images in firefox3.1b3 with xf86-video-ati covered with
                    black rectangles
           Product: xorg
           Version: 7.4
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: yoshi314 at gmail.com
         QAContact: xorg-team at lists.x.org


i'm using current git head from main xf86-video-ati branch. 

when i've updated it yesterday most images in firefox started to look as if
they are covered 90% with black rectangle (there is a narrow visible vertical
stripe of the picture, at the left edge, or sometimes in the middle; the rest
is black).

the behavior is irregular, sometimes the images are missing, or invisible
(probably covered with a rectangle that has a color of the background of the
webpage). 

reverting to commit bbfd4625478e37d10fd58b23f46153f349370a52 seems to help.
i'll try to narrow it more precisely in a few hours.

i'm using xorg-server 1.5.3 with git ati driver. 

my graphics card is 

05:00.0 VGA compatible controller: ATI Technologies Inc RV515 PRO [Radeon
X1300/X1550 Series]

i'll provide screenshots, if needed to ilustrate the issue (assuming the
problem will be visible on the screenshots). 

adding Option  "XAANoOffscreenPixmaps" "true" in xorg.conf does not seem to
help (which is what i found when looking for solution).

i've only seen the problem in firefox, video playback and image browsers do not
seem affected.
