1px wide vertical dead area on screen when Desktop Wall plugin enabled

[Timo Palomaa]

When Desktop Wall plugin is enabled, 1px wide non-clickable horizontal area/line appers in the right side of the screen. Everything draws correctly on the area, but it is not clickable.

See the illustration as the attachment (purple = screen, black = the dead area).

* this does not appear on my secondary display, but does appear on the primary display even if dual display is disabled
* I had this issue already before upgrading to 13.10 and while doing that, I also resetted all Compiz settings and re-loaded my profile configuration file
* on another account on this computer I can not repro this just by enabling Wall
