Derham:

A minor gripe with is display recently is that the screen now flashes during an OTA update. I’ve found a solution…
Add the on_begin section to the OTA block to turn off the backlight.
ota:
  platform: esphome
  password: !secret web_server_password
  on_begin:
    - switch.turn_off: lcdbacklight

Have you seen: Guition esp32-p4-jc1060p470 - #10 by clydebarrow - Clyde’s added a execute_from_psram esp32 option which also may help.
