I have actually temporarily solved it by playing with the backlight pin. Disabling it for ~100ms during turn on hides the issue pretty well. 😄 |

Unfortunately it takes time to configure the display after power up. Not all displays show garbage at power up, most show a black or white screen. |

As the title says, I am wondering if it is possible to avoid the junk screen (many random pixels, white and colored) that appears for a brief period of time?
The driver used is
ST7789_DRIVER
. Maybe there is something that I can feed before the library is initialized? Or maybe it's just inherent issue of the display/driver?The screen I am talking about:
Subsequent soft restarts do not have this junk screen, only during power on.
