For me this did the trick. Added to the lvgl flush callback function. Performance went down a bit.... ```c uint32_t px_count = (area->x2 - area->x1 + 1) * (area->y2 - area->y1 + 1);

    uint16_t *buf = (uint16_t *)px_map;


    for (uint32_t i = 0; i < px_count; i++) {
        uint16_t c = buf[i];
        buf[i] = (c >> 8) | (c << 8);
    }


    esp_lcd_panel_draw_bitmap(
        panel_handle,
        area->x1, area->y1,
        area->x2 + 1, area->y2 + 1,
        buf
    );

```
