           Summary: R700, DRI2, KMS: minor mouse pointer corruption
           Product: xorg
           Version: unspecified
          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: nightmorph at gentoo.org
         QAContact: xorg-team at lists.x.org

So the new KMS support in .32_rc2 and git driver stack for my R700 card works
great! Except that there's some minor mouse pointer corruption. The corruption
is not present when using the mouse in Firefox, or when the pointer changes to
anything other than the default "arrow" pointer whether in Firefox or just in
my Xfce desktop or in another application.

The corruption manifests itself as a series of three small dots hovering over
the default "arrow" pointer. It appears on xfdesktop, xfwm4, and within all
other opened applications in my Xfce environment...except Firefox, curiously

I'm using the very common "Vanilla DMZ Xcursors" theme from:

This error did not appear with the old xorg-server 1.6.3.x, libdrm-2.4.13,
video-ati-6.12.4, and mesa-7.5.1--the "stable" stack for Gentoo.

mesa master: EGIT_VERSION=be16acaafa2f28bb7d4551ed93d2e290c928006c
libdrm master: EGIT_VERSION=04495eeec2f053be17a10cc82e646a1e23ed3830
xf86-video-ati master: EGIT_VERSION=cc45856a18dd3e6f7e44d9eb507b31419da70977
xorg-server: 1.6.4
kernel: 2.6.32-rc1-git3
dri2proto: 2.1

I'll attach Xorg.0.log, dmesg, xorg.conf, and screenshots.

(An aside: thanks so very much for the amazing progress made in xf86-video-ati
and the rest of the stack for R700 cards. I bought this card some months ago
specifically because of the driver support that would one day roll around. Yes,
just like in the XKCD strip: http://xkcd.com/644)
