Today I was faced by an odd behavior that is: when opening the page in chrome it was displayed in a larger resolution than the normal one which led to some tabs in the page being invisible.
I figured out a solution to this weird issue by doing a java script hack as follows:

Create a Javascript executer.
WebDriver driver = new ChromeDriver();
JavascriptExecutor jsExecuter; = (JavascriptExecutor) driver;  

Execute this java script command against your web driver 

js.executeScript("document.body.style.zoom='90%'"); 

//Do the required actions in the tabs

After all is done, don't forget to reset the browser to its default settings.

js.executeScript("document.body.style.zoom='100%'");
