Only two things I can think of:
1. Poor wire connection somewhere, most likely LCD display wire, or power wire.
2. Power is being interrupted briefly?
If it is a LCD display wire connection issue, I think if you switch screens on the rotary encoder, it will re-initialize the LCD screen, removing the random text/symbols.
