@ahmadnasriya Yeap I’ve checked if everything is fine with the older versions of Safari
and here is what I’ve got
- On latest Big Sur and Safari 14.0 and I saw the problem we were talking about.
- All thing works fine on Catalina with Safari 13.1
- I’ve also checked the Mojave and Safari 12.1
And the input works just fine on it as well. Calculations were right and without delays.
So this is a problem of Safari new 14.0 version of Big Sur OS
I think it will be fixed by Apple with the update 14.1.
