Dear Gustavo, Thanks you very much for your interested and for the informations you've provided.
I wasn't aware that the esp-wrover-kit doesn't have any touch keypad, I am very much surprised about that. That's why I talked about an improper lvgl operation, I was expecting to interact with the display as I do normally with many other boards :) I think this is a weakness of the esp-wrover-kit, do we have to use a separate keypad in case a user entry is required? On the other hand the display is not stable, it moves up and down as seen on old-time TVs, it is a synch problem, it can be related to frame rate, I will try overclocking the SPI bus as you've suggested.
