When you change  for example the clock in .ioc (like from 48 MHz to 20 MHz) and even change it back to 48 MHz, your display stops working properly (colors not showing). TFT st7789v display and stm32h753vit6 microcontroller please solve my issue.

Diff the code you have now vs the code you had when it was working.
