Screen and Touch Display plugin makes DAC unhappy - Help and Support - Volumio Community
rotate screen will take a lot of “source” and may cause problem,
have you tried remove the rotate command, let the screen use it’s native “vertical” view, and test if any skip track ( though the peppymeter size will be cut )
Have you tried set Touch Display GPU memory to 128mb and rotate the screen using Touch Display Setting instead of display_rotate=1 command ?
