Cache disabled but cached memory region accessed

Hi all

I am trying to update my project with this library from version 0.2.1 to version 1.2.0. In my project, I use a Waveshare ESP32-S3 Touch-LCD 7 Zoll. > I have replaced all the necessary files and configured everything as described in the guide or as I had done before. When I do not initialize the display, the code runs as expected. However, as soon as I add the following code, even without writing to the screen,I receive the below error.

Tearing Mode is set to 3.

Board* board;

// inside setup
    board = new Board();
    board->init();

#if LVGL_PORT_AVOID_TEARING_MODE
    // When avoid tearing function is enabled, the frame buffer number should be set in the board driver
    board->getLCD()->configFrameBufferNumber(LVGL_PORT_DISP_BUFFER_NUM);
#endif
#if ESP_PANEL_DRIVERS_BUS_ENABLE_RGB && CONFIG_IDF_TARGET_ESP32S3
    auto lcd = board->getLCD();
    auto lcd_bus = lcd->getBus();
    /**
     * When using "ESP32-S3 + RGB LCD" to operate WiFi or flash, the screen may drift. We need to enable the
     * `RGB LCD Bounce Buffer + XIP on PSRAM` feature to avoid this issue.
     * See FAQ section in README.md for more information.
     */
	Serial.print("LCD Bus Type: "); Serial.println(lcd_bus->getBasicAttributes().type);
    if (lcd_bus->getBasicAttributes().type == ESP_PANEL_BUS_TYPE_RGB) {
        static_cast<BusRGB*>(lcd_bus)->configRGB_BounceBufferSize(lcd->getFrameWidth() * 20);
    }
#endif
    assert(board->begin());

Hi @minou65,

I think you can also refer to #193 (comment).
