Problem: On https://turbovision.in6-addr.net a tiny-background-size + background-repeat tile over a large painted area crashed WebContent. Cause: BackgroundPainting was recording one paint command per tile for any repeating background that’s not a decoded image. A small tile over a large area could produce literally millions of commands — resulting in a display list exceeding MAX_MESSAGE_PAYLOAD_SIZE, and tripping an assert. Fix: When a repeating AbstractImageStyleValue would emit more tiles than a fixed threshold, record a single tile into a nested display list and, reusing some existing SVG pattern machinery, fill the coverage rect with a PatternPaintStyle. We render the tile once, and repeat it with a tiling shader — so the display list holds a single command regardless of tile count. Normal backgrounds keep their exact per-tile painting.
