Hi Murat, The LVGL moving up and down it not a bug, it is by design.
LVGL guys did it as as way to show all the screen exactly for board that doesn't have a touchscreen to interact with it. Otherwise you should think it was crashed/freeze, don't you? :-) Hmm, maybe we can use a BackBerry TouchPad as mouse. Matias, do you think it is possible? Probably we will need to implement a driver to make it behavior like a mouse to be used on NuttX.
