invisible grid in current CVS

[Allin C. <cot...@wf...>]

I'm comparing the grid lines shown by gnuplot 4.6.5 and gnuplot 5.0 rc1 
(CVS as of 2014-07-25) for the following script:

set term pngcairo
set output 'test.png'
set grid ytics
plot sin(x)

In 4.6.5 the grid is fairly discreet but clearly visible. In CVS it's 
pretty much subliminal, barely visible. Is this intended?
