How to remove the scrollbar ?

[JakFlew]

When a page is captured, a scroll bar appears on the right side. How do you get rid of it?

[vpinv]

I think you can increase the delay after every scroll to get rid of scrollbar

[JakFlew]

Can you explain it in detail?

Add this line to the import section in your class:
import org.openqa.selenium.JavascriptExecutor;

And add this line inside your method before taking the screenshot:
((JavascriptExecutor) driver).executeScript("document.body.style.overflow = 'hidden';");

It worked for me.

If solution from natalygoloborodko doesn't work try:

driver.executeScript(
                "var style = document.createElement(\"style\"); style.innerHTML = \"::-webkit-scrollbar {display: none;}\"; document.body.appendChild(style);");
