           Summary: [evergreen] X server crash in
                    EVERGREENDownloadFromScreen() when starting certain
                    apps
           Product: xorg
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: thomas.lindroth at gmail.com
         QAContact: xorg-team at lists.x.org


I use an xrandr desktop with two monitors connected to hdmi and vga. When
starting gnuplot the 2nd head connected with vga gets corrupted. The contents
of the first screen is copied to it. Redrawing windows will make them display
correctly again so I often drag a windows all over the 2nd screen to repair it.
This often cause the X server to segfault.

I've had this problem for a while now. I used to get the same error when
starting gimp but that works fine now. As far as I can tell this only happens
with gnuplot and gimp. Using an Evergreen cedar card with xorg-server-1.10.2
and linus kernel, mesa, xf86-video-ati, libdrm compiled from git as of today
from gentoo live ebuild. I'm running a standard Kde-4.6.4 desktop.

Nothing shows up in dmesg and Xorg.0.log just shows the usual "Caught signal
11" error. My xorg.conf is empty except for a few font paths and LogVerbose
serverflag.
