Release v0.1 has the display created by the LVGL library using the lv_tft_espi_create() function. However, quickly changing objects exhibit image flickering / tearing, due to a relatively poor display performance for the task, even with the highest possible SPI frequency set (80MHz) for this hardware (ESP32-S3):

After using two buffers and DMA (v0.2 release):

In other projects where the TFT_eSPI library is utilized directly, the programmer can use something called Sprites, which are graphics buffers that minimize flicker and tearing effects. Such a feature is not present in the LVGL -> TFT_espi integration.

After checking LVGL documentation on how to speed up the UI, this example project will attempt to implement the same slider using two buffers and a flushing function with DMA, to get a smooth motion for quickly moving objects, like the slider in this program.
