I have the following setup:
Twinview with nvidia drivers:
    Option         "TwinViewOrientation" "RightOf"
    Option         "TwinView" "1"
    Option         "TwinViewXineramaInfoOrder" "DFP-0, CRT-0"
    Option         "MetaModes" "DFP-0: 1920x1200, CRT-0:1280x1024; DFP-0: 1920x1200"

Left Monitor (external,main): 1280x1024
Right Monitor (notebook): 1920x1200

Plasma panel is drawn not completely on the left monitor, with some artefacts on the right monitor (see screenshot).
I am using current 4.1 snapshot from Suse Buildservice for 10.3
It should be drawn completely on the left screen.
Plasma related configfiles have been removed before starting plasma, so fresh config is used.
