  To continue...
  I still have the LGFX write frequency set to a lower value
  cfg.freq_write = 15500000
  In fact if I set it to almost anything else (e.g. 16000000 or 14000000) the noise on the rendered image is worse.

  Hi,
  To answer your questions.
  1) I have previous projects using the basic 7" esp32-s3 display, and I have just bought 3 of the advance esp32-s3 to upgrade my projects
  2) yes , see 1)
  3) Yes I did modify the original program using your example code for the advance, but when it didn't work I tried your factory example code, which also didn't work.

  Some updates from my side...

  • The PSRAM frequency should be 80MHz, 120MHz is experimental, and doesn't work for me.

  • Also the cache fix flag doesn't apply to the S3, so I removed it from the build config
    Updated flags are now:

    -DBOARD_HAS_PSRAM
    -DPSRAM_SIZE=8
    -DPSRAM_CLK=80000000

  This change enables me to use PSRAM (sort of). I have 3 advance screens, flashing all 3 with
  the same binaries gives slightly different results. One display seems pretty solid,
  no issues with flicker/updates. The second flickers a little, the third constantly flickers on the side nearest the USB socket.
