hi
i have same problem in esp32
from liquidcrystal_pcf8574.
@tiny-eng solved it by calling lcd.begin () periodically in the loop, for me it was enough to call it once every 20 seconds.

@tiny-eng I'm glad you fixed the problem.
In my case I had the pins well soldered and the LCD seemed stable, but as time passed (between 20 min to approximately 1 hour) I lost control of the LCD and it showed random characters (it also happened if an electric motor was activated nearby).
so I decided to use the lcd.begin() periodically to get the LCD back.
It may also be that the LCD or LCD driver that I use is of poor quality (I bought them through aliExpress)
but I don't know exactly.
