【Q】 Do I need to modify this library to use it on my Japanese NTSC-J standard TV? #15

Hello. @Roger-random I am grateful to be able to use your library. Thank you.👍

I wrote your library into lolin32 and tweaked it into the composite input of a Japanese SHARP digital TV. When I did so, I was able to display the text and graphics, but the text and graphics oscillated up and down periodically. I am not sure, but I am wondering if there is something wrong with the vertical sync signal. Is this library not compatible with "NTSC-J"? How can I correct the vertical oscillation of the display?

Thank you very much for your help.

PS Maybe it's just noise coming from the ESP32 board.
