I made two logs playing an mp3 with left only or right only channel with the vu meter style 2 as I hope they can help you resolve that issue
Last I heard, that issue was resolved ?!?!
You'll need to post a picture (or short video if possible..)
The update to fix the custom characters may have broken it.... But the logs show the correct characters being sent to the display... SO I need a picture to figure out what character definitions are being used by the display.
