Cursor Subpixel Fringe

A full-bleed field where every grid cell carries three thin vertical luminance slivers standing in for an LCD's physical red/green/blue subpixel stripes. Near the cursor, or the idle sweep target when nothing is pointing, the three slivers of a cell splay apart and diverge in value, as if a renderer were locally re-hinting glyphs to the pixel grid. The whole field shimmers at rest, not only under the pointer.
