Hmmm.  Version 4.6.x you say?
How about creating using a heavy border for the backing rectangle rather
than relying on a coordinate offset?  The border line won't get clipped, so...



set term pdfcairo background rgb "olive"
set output "shadows.pdf"

set object 1 rectangle from graph 0,0 to graph 1,1 back 
set object 1 fs solid fc rgb "white"
set object 2 rectangle from graph 0.05,0.0 to graph 1.0,0.95 behind 
set object 2 fs empty border -1 lw 15

set multiplot layout 2,2

plot sin(x)
plot cos(x)
plot sinc(x)
plot erf(x)

unset multi
