Subpixel scroll issue, can't set scrollTop properly on Chrome 69
I think it might be related to the resolution of the monitor.
I have a resolution of 1920x1080 and with a scale of 100% the result is 75.
But if you set 75% or 150%, the result will be 74.66666412353516.
Or say 25%, the result will be exactly 74.
I don't have any exact answer as to what it might be related to, but I think this little research might lead to the right path.
