STM32F7690-DISCO .. Just run the LCD Brighrness function and the screen is broken.

[Lbbby]

Function Use

    HAL_DSI_ShortWrite(&hdsi,LCD_OTM8009A_ID, DSI_DCS_SHORT_PKT_WRITE_P1,OTM8009A_CMD_WRDISBV, (uint16_t)(value * 255)/100);

....

If you adjust the backlight in real time, the screen will break.

Just curious if you somehow figured out what this was. I don't remember having seen or heard about this issue before.
