I have same issue reference to https://github.com/szimek/signature_pad/issues/76
I have an app which is locked in portrait mode but my signature screen should rotate in landscape as design specs suggests. I rotated the screen in landscape using CSS which works fine but when I try to write a signature, the drawing begins either off screen or opposite of the input and in some instance it draws in the opposite direction.
CSS which I used is
transform: rotate(-90deg);
transform-origin: left top;
width: 100vh;
overflow: hidden;
position: absolute;
top: 100%;
left: 0;
I used the solution of github issue mentioned in question but no help, I tried Signature Pad does not follow cursor this solution also but did not work for me.
You can observe the behaviour of cursor and signature getting written on here
Any help would be appreciated. Thanks.
