When a plate is imaged as overlapping Keyence montage tiles, Plate Montage View previously cropped each tile to its center and placed them edge to edge. Because the tiles genuinely overlap, every seam repeated features that appear in both neighbours — cells and colonies near a boundary could show up twice. The well page never had this problem, since well images are properly fused mosaics, so the two views disagreed about the same well.
Stitched View now renders a true stitched plate image built from those same fused well images. The plate view and the well view finally show the same thing, and features near tile boundaries appear once, where they actually are.
