Not sure what causes this, not lack of mosaic although I guess it could conceivably be blending issues. More likely a real bug with tile rendering on those lines.

At this point in the game all 4 backgrounds are enabled along with objects, the main background is BG3, others sit on top of it. BG3 is 256*512 at 4bpp and unsurprisingly the broken tiles are all those which are displayed in the second of those screens.

It seems pretty clear that the next step will be debugging calculation of tile map address based on large screen backgrounds
