[SOLVED] ATI Catalyst / Xorg issue with Multihead (3monitor)

Question

i'm having problems for a long time, with different versions of the ATI Catalyst driver and Xorg,
right now i'm using this versions,
catalyst-hook 11.2-2
catalyst-utils 11.2-1
lib32-catalyst-utils 11.2-1
xorg-server 1.9.4.901-1
xorg-server-common 1.9.4.901-1
xorg-server-utils 7.6-2
the catalyst package are from the catalyst server recommended by the Arch Wiki
http://catalyst.apocalypsus.net/repo/catalyst/x86_64
the problem that i have is that when i try to pass from one monitor to another, when
i pass to the 3rd one the X crashes, this happen always with the same monitor no matter what.
here is the backtrace from the startx logs,

i wanted to know if there is any official forum / bug tracker  of amd/ati where report this bug,
or if one of you had this kind of problem before and can give me a hand to resolve this, i would be grateful.
here is the ati report about the system info,

Answer 1

solved!
since the cursor used through the proprietary catalyst driver have issues, use instead the SW cursor,
Section "Device"
Option "SWCursor" "true"
EndSection
