Waveshare 3.5 "pico" device tree

[notro]

I looked at the fbtft_device entry:

		.name = "ili9481",
		.spi = &(struct spi_board_info) {
			.modalias = "fb_ili9481",
			.max_speed_hz = 32000000,
			.mode = SPI_MODE_0,
			.platform_data = &(struct fbtft_platform_data) {
				.display = {
					.regwidth = 16,
					.buswidth = 8,
					.backlight = 1,
				},
				.bgr = true,
				.gpios = (const struct fbtft_gpio []) {
					{ "reset", 25 },
					{ "dc", 24 },
					{ "led", 22 },
					{},
				},
			}
		}

It says regwidth=16. So I looked at the display schematics and yes it has a 16-bit shift register.
Try adding regwidth = <16>; to the device tree.

Thank you very much.
The behavior of the display changed, and the text seems to be wrapped now and some lines are missing, but the cursor is blinking in the very last line under the word 'distribution':

Subsequently, I also tried to switch width/height:

And it's working now. Thank you very much for your help.
