Hello all,

I'm writing a file to PNG on Windows 7 using 'cairo-png'. I've been using
it without problem for a while, but abruptly I'm getting what look like
unplotted areas. I'm using the cairo-png specifically because it
sucessfully generates a transparent background, whereas 'windows' doesn't.

The actual issue has a lot of code I don't think it's useful to post, but
the relevant lines of code are below:

png(file="FooBar.png",
w=900,h=500,units="px",bg="transparent",family="Lato",type="cairo-png",antialias="none")
par(mar=c(5,4,3,0),bty="n",mfrow=c(1,2))
dev.off()

You can see the difference in outputs here:

Note that using 'windows' does not result in the error - it's something
specific to 'cairo-png'. The vertical lines appear to be empty, i.e.
transparent.

Any guidance or assistance would be greatly appreciated.

Regards,
Daniel Egan
