Same problem here. Figured out how to reproduce it…seems to only be a problem when the volume meter is displayed at the same moment when the scrolling display shifts from one line (e.g. the album name) to another (e.g. the track name).
I had the player on shuffle, and wanted to see the track’s name, so just wiggled the volume one “click” up/down, to keep the screen lit (rather than adjust the time limit to dim the screen).
