Display, idle mode displays strange on GC9A01 from ili9XXX

I need to sqeeze the power consumptions,
I’ve added the “Idle mode on” command to the initial command sequences, ili9XXX display driver,
the command is,

{“cmd”: 0x39, “data”: bytes([0])}

It displays strange, I’ve attached a video.
enviroments are ESP32, mp port, gc9a01 lcd display.
ili9341 also has idle mode, but I haven’t tested it.
