When a WMS layer requires several map requests (because the viewport image size is bigger than the maximum allowed tile size), some corner tiles are not drawn.
The problem can be reproduced by loading any WMS server (for instance http://geoserveis.icc.cat/icc_mapesbase/wms/service), maximixing the window of the view (to ensure several tiles are requested) and then panning the map up and right (to don't be centered on the layer extent). Try panning several times up and right and at some point one of the tiles will not be drawn.

This happens because a part of the tile is outside the layer extent, and therefore only the relevant part of the tile is requested in LyrWMS. However, the extent and affine transform is not updated accordingly, and the the tile is not visible on screen (probably it is drawn somewhere, but outside the visible area).
