Xorg log

Hello,

My graphic card is 
01:00.0 VGA compatible controller: ATI Technologies Inc RV710 [Radeon HD 4350] (prog-if 00 [VGA controller])

If I specify no particular option to xorg I get little black and grey bars.
See attached screnshot.

If I add the lines below in a conf file there is no corruption except
when I the confirmation box is displayed when I logout from KDE. 
Section "Device"
   Identifier "Device0"
   Option  "RenderAccel" "off"
EndSection

Systel id fedora14
xf86-video-ati and mesa are from today's git master.
libdrm-2.4.22-1.fc14.x86_64
xorg-x11-server-Xorg-1.9.1-2.fc14.x86_64
xorg-x11-server-common-1.9.1-2.fc14.x86_64

Regards,
Benoit

I have added "irqpoll" quirck for the kernel to take IRQ used by USB for mouse
and keyboard.
Not sure it can be related.

Corrupted screen of firefox taken using ksnapshot

Screenshot of firefox window showing typical corruption.
It also happens on the background and on the panel.

Is this a recent regression in git?  If so, can you bisect?

I cannot tell if this is a regression as I got this second hand hardware recently.

The original Radeon X300 card worked ok.
Only when I swapped it for an HD4350 I started to see those corruptions.
I also tried with a friend's HD4350 from another brand and see the same corruption.

I went back to the commit below and still see the corruption.

    Convert x(c)alloc/xfree to m/calloc/free.
    
    Fixes deprecation warnings with xserver master and should also work with older
    xservers.

The corruption are visible:
1. on the KDE panel,
2. on the bubbles that show up when cursor is over an icon on the panel or the desktop,
3. on the backgroud when KDE asks for confirmation to logout,
4. on regions of windows that are shown just after beeing scrolled behind the panel. Looks like panel corruption gets replicated on the windows (this is with desktop effects disabled).

With Gnome I have observed only problem number 3.
