I have set up moc without any problems added a new theme, then noticed start up was slow.

Moc is telling me Layout1 syntax has changed, could not get full console directory to '#'ed out Layout1. Now using key 'l' to hide playlist.

Can someone tell me the correct syntax for a full screen directory layout? Could theme change how layout works?

The syntax of the Layout options has indeed changed in the SVN
version of MOC (r2357). If you follow the message's advice to
the example configuration file you will find instructions on the
new format.

To get full screen directory and playlist panels:

Layout1 = directory(0,0,100%,100%):playlist(0,0,100%,100%)

The themes cannot affect the layout, but setting various fields to
have the same forground and background colours may hide them.
