lv_disp_set_rotation do not work !!!

[MinhDuc-HCMUT]

Hello, please help me!!!
I run esp32-smartdisplay-demo and working fine! But when i add line lv_disp_set_rotation(disp, LV_DISPLAY_ROTATION_90);, screen do not display anything

#include <Arduino.h>

#include <esp32_smartdisplay.h>
#include <ui/ui.h>

void OnAddOneClicked(lv_event_t *e)
{
    static uint32_t cnt = 0;
    cnt++;
    lv_label_set_text_fmt(ui_lblCountValue, "%u", cnt);
}

void OnRotateClicked(lv_event_t *e)
{
    auto disp = lv_disp_get_default();
    auto rotation = (lv_display_rotation_t)((lv_disp_get_rotation(disp) + 1) % (LV_DISPLAY_ROTATION_270 + 1));
    lv_display_set_rotation(disp, rotation);
}

void setup()
{
#ifdef ARDUINO_USB_CDC_ON_BOOT
    delay(5000);
#endif
    Serial.begin(115200);
    Serial.setDebugOutput(true);
    log_i("Board: %s", BOARD_NAME);
    log_i("CPU: %s rev%d, CPU Freq: %d Mhz, %d core(s)", ESP.getChipModel(), ESP.getChipRevision(), getCpuFrequencyMhz(), ESP.getChipCores());
    log_i("Free heap: %d bytes", ESP.getFreeHeap());
    log_i("Free PSRAM: %d bytes", ESP.getPsramSize());
    log_i("SDK version: %s", ESP.getSdkVersion());

    smartdisplay_init();

    __attribute__((unused)) auto disp = lv_disp_get_default();
    lv_disp_set_rotation(disp, LV_DISPLAY_ROTATION_90);
    // lv_disp_set_rotation(disp, LV_DISP_ROT_180);
    // lv_disp_set_rotation(disp, LV_DISP_ROT_270);

    ui_init();

    // To use third party libraries, enable the define in lv_conf.h: #define LV_USE_QRCODE 1
    auto ui_qrcode = lv_qrcode_create(ui_scrMain);
    lv_qrcode_set_size(ui_qrcode, 100);
    lv_qrcode_set_dark_color(ui_qrcode, lv_color_black());
    lv_qrcode_set_light_color(ui_qrcode, lv_color_white());
    const char *qr_data = "https://github.com/rzeldent/esp32-smartdisplay";
    lv_qrcode_update(ui_qrcode, qr_data, strlen(qr_data));
    lv_obj_center(ui_qrcode);
}

ulong next_millis;
auto lv_last_tick = millis();

void loop()
{
    auto const now = millis();
    if (now > next_millis)
    {
        next_millis = now + 500;

        char text_buffer[32];
        sprintf(text_buffer, "%lu", now);
        lv_label_set_text(ui_lblMillisecondsValue, text_buffer);

#ifdef BOARD_HAS_RGB_LED
        auto const rgb = (now / 2000) % 8;
        smartdisplay_led_set_rgb(rgb & 0x01, rgb & 0x02, rgb & 0x04);
#endif

#ifdef BOARD_HAS_CDS
        auto cdr = analogReadMilliVolts(CDS);
        sprintf(text_buffer, "%d", cdr);
        lv_label_set_text(ui_lblCdrValue, text_buffer);
#endif
    }

    // Update the ticker
    lv_tick_inc(now - lv_last_tick);
    lv_last_tick = now;
    // Update the UI
    lv_timer_handler();
}```

I want to get used to rotating the screen for my future projects.

Will have to verify this. LVGL made changes to the rotation so compiling failed.
Should be fixed in the current release 2.1.0
