I have ILI9341 320x240px TFT LCD screen which I am using with ESP32-S3-wroom-1 module.

I have tested with TFT_eSPI and works fine, but when using LVGL, I am seeing weird artefacts on the edges.

I am using Arduino IDE

Started off the sketch from

https://github.com/lvgl/lvgl/blob/master/examples/arduino/LVGL_Arduino/LVGL_Arduino.ino

Havent changed sketch file much.

I am using LVGL latest v8.2.0

/*====================
   COLOR SETTINGS
 *====================*/

/*Color depth: 1 (1 byte per pixel), 8 (RGB332), 16 (RGB565), 32 (ARGB8888)*/
#define LV_COLOR_DEPTH 16

/*Swap the 2 bytes of RGB565 color. Useful if the display has an 8-bit interface (e.g. SPI)*/
#define LV_COLOR_16_SWAP 1

/*Enable features to draw on transparent background.
 *It's required if opa, and transform_* style properties are used.
 *Can be also used if the UI is above another layer, e.g. an OSD menu or video player.*/
#define LV_COLOR_SCREEN_TRANSP 1

/* Adjust color mix functions rounding. GPUs might calculate color mix (blending) differently.
 * 0: round down, 64: round up from x.75, 128: round up from half, 192: round up from x.25, 254: round up */
#define LV_COLOR_MIX_ROUND_OFS 0

/*Images pixels with this color will not be drawn if they are chroma keyed)*/
#define LV_COLOR_CHROMA_KEY lv_color_hex(0x00ff00)         /*pure green*/

LV_COLOR_SCREEN_TRANSP 1 was originally 0 changing it did not change anything.

Any help will be greatly appreciated.
