M5StickC plus Screen issues, lines on screen

[teflon121]

I have a brand new M5stickCplus, I feel like the screen is broken somehow.

I have feint lines on the screen that run vertical or lengthwise depending how you think about it. The seem to be part of the last screen or code I put on them. Like a ghost of the last code I burn onto it. Its odd.

Now only after letting it sit for a day or so, do the lines disappear once turned on again.

What is making these ghost lines appear and disappear ?

Thanks
