the display is not smooth

I installed the latest version of volumio, on rapberry pi 4 by enabling the display. I connected a 7inch HDMI Display-C touch display with 1024 × 600 resolution. everything works very well, but the touch is not smooth and the response on the display is delayed. it’s normal? how can i solve?
thank you all.

@gvolt can you help him with the display :wink:
