           Summary: Corruption and slowness when screen rotated 90 degrees
                    left or right
           Product: xorg
           Version: 7.3
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: jlp.bugs at gmail.com
         QAContact: xorg-team at lists.x.org


I have a laptop HP Compaq nx6325 which has an integrated Radeon graphics:
01:05.0 VGA compatible controller: ATI Technologies Inc RS485 [Radeon Xpress
1100 IGP] (prog-if 00 [VGA])
I installed the beta drivers version 6.7.195.
What I noticed is that if I rotate the screen 90 degrees left or right there is
a screen corruption in the lower 1/4 part of the rotated image. I also noticed
that drawing gets very slow if rotated this way. It is very noticeable when
moving windows around for example.
If screen is rotated 180 degrees I don't experience any of these problems.
