Press event delay (~180ms) for touchscreens
Dear libinput team,
I'm using Ubuntu 20.04.3 and tested two different touchscreens (ELO Touch / Iiyama). With both touchscreens I have an issue when it comes to button down visual feedback (browser, Qt, other gui frameworks). The button down event (press event) comes with a ~180ms delay. As I read in existing issues it might have something to do with the tap-and-drag option. I tried to deactivate it, but both screens are not listing this option. Even when I set this option in the libinput config for touchscreens to false it has no effect.
Is there any other solution to get rid of the delay?
Kind regards
Nils
