Finding 290 made ENABL/GRP1/VDELBL selection beam-aware, but the renderer still painted the ball's width, color, position and motion from the end-of-line snapshot. A mid-line CTRLPF, COLUPF, RESBL, HMBL or HMOVE write could therefore retroactively alter pixels the beam had already crossed.

Raw traces, ROM material, local paths, and personal data are not part of this public record.
