           Summary: Sometimes X shows strange horizontal lines and random
                    dots in images when using radeon driver, after shutting
                    down X, screen is blank
           Product: xorg
           Version: 6.8.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: mrsteven at gmx.de


When I viewed some povray rendered images yesterday, I noticed some strange
horizontal lines and random dots in all images. When I moved the image window or
resized it, the lines and dots moved to another position within the image. 
After switching to a text console with ctrl+alt+f1 and going back to X with
ctrl+alt+f7, the lines and dots disappeared, but after shutting down X, I ended
up with a blank screen (maybe that is related to this problem).
Since most of the pictures are .png, but some are .bmp, I'm really sure, that
this is a bug in Xorg, also because I noticed the problem in Kuickshow,
Konqueror and Mozilla.

I use:
* Gentoo Linux
* xorg-x11-6.8.0-r1 from portage (should be almost the same as the official
xorg-6.8.1)
* radeon driver from xorg, with an ATI Mobility Radeon 9600
* vanilla Kernel 2.6.9 without framebuffer
* sys-libs/glibc-2.3.4.20040808-r1
