           Product: WebKit
           Version: Safari 11
          Hardware: All
                OS: iOS 11

You can view the issue here: https://jsfiddle.net/4bL3zv74/
Compare to here where the input looks fine when the canvas isn't drawn on: https://jsfiddle.net/buxfmgzq/

See this link for an example of the bug where we noticed it originally. This one seems most noticeable on mobile devices: https://www.pdftron.com/webviewer/demo/viewer.html?d=../../xod/change_of_address.xod

This occurs in Safari on macOS as well as iOS and doesn't occur in any other browsers.
