When you use Applitools for testing, it is important to keep all pages in the same state as they used to be when the baseline Applitools screenshot was taken. In Applitools visual difference means a bug. This is why a blinking caret (cursor) can become a problem when the baseline screenshot was taken with a caret either visible or invisible, as long as the actual screenshot was captured with a different state of the caret. We can avoid this issue if we hide the caret by making it transparent before taking a screenshot in Applitools. This is how we can do it in Selenium Webdriver (Javascript bindings) (assuming that you initialized the driver object with Webdriver).
