That is insane, and not good. Hopefully yours is still under warranty; it does appear something is pressing the top left of the screen constantly (possibly a fiber that got inside the screen?) but I would take it to a local service location or your Yamaha dealer immediately. Yes, dust covers are only good if the cloth doesn't leave behind fibers.
