With the dual-monitor setup I'm struggling to understand the panning option. I have looked at https://wiki.archlinux.org/index.php/xrandr and the man file and still couldn't figure that track x track y part out. It's not very easy to understand.
The panning option might be there as a workaround for a bug in xorg. Since xorg 1.20 the patch to resolve that should be included, so you can try your configuration without panning.
