Public bug reported: I have a multiple monitor setup and the pointer barriers seem to have a small (~1px) gap at the edge of the screen. For example in gnome-shell, the panel has barriers on either end, If I move the mouse towards the hot corner (top-right corner of screen) it inevitably just slips over the top of the barrier and onto the next monitor.
This bug introduced by the '500_pointer_barrier_thresholds.diff' patch. I have rebuilt the xserver without this patch, and the barriers behave as expected blocking/trapping the mouser pointer in the top corner of the screen.
