Nice video 👍👍👍.

Best method for such problem will be to tighten or loosen the screw behind the i2c module in a small blue box(potentiometer of display) it will change the contrast of display due to high or low contrast these boxes appear.

Hi I have the same issue. However, I am using CubemX Uvision STM32F103C8T6 mp i checked all solderings and they are looking good. Also, I am using 10k potentiometer when i increase the pot level white squares are going but when i decrease the pot level white squares are appearing on my LCD. What can be the issue ? Note : by the way i am using another psu for LCD, GND's are interconnected.
