Fast capacitive Touchdisplay

Hi all,

I‘m a neewbie to Arduino.
Currently I use a Touchdisplay (%product-title% kaufen) on an Arduino Uno Wifi Rev2.
Everything is working fine, but the drawing of components on the screen is really slow. I use the UTFGLUE class with MCUfriends from Vellemann VM420.

What can I change to make the display faster?

Is it on Atmel Chip or is the display slow (only a few Pins) or is it on the code?

Is there a better configuration (other display, other chip…)? Do you have good proposals? I also prefer a capacitive Display.

Best regards and thanks.
