Rasperry Pi 4
Codesys MC for Raspberry 4.6 with Webvisu per Touchscreen.
I am reading the Keyboard events with evdev for some other things. The problem is when a keyboard Key is on hold, Codesys Touch Screen reaction is extreme latent/slow. Though i can see in events log that the touch events are registered.
Any Help!

I'm not sure if this is what you are referring to, but maybe it helps:
