The tiles appear to have transparency on the sides as opposed to WMS which fully covers the area

workaround found, setting:

<metabuffer>1</metabuffer>

Some notes:

metabuffer makes 258x258 requests which don't have gaps.
changing grid zoom levels makes different sets of gaps appear at different locations.

Workaround for vs/client serving WMS layers with special rendering (other than default layer) is setting gutter parameter > 0.
