Anet display malfunction

It starts looking like hieroglyphics sometimes. It's not every time but it starts messing up after I hit print.

It's not octoprint's fault.
The display cable got no shielding so that can happen from time to time.

There are several options:

  • shield the cable
  • use a ferrit bead
  • route the cable as far away as possible from components that generate electro magnetic interference
  • press the center button to refresh the display when it happens
