I'm using chromedriver 2.30 & chrome browser v60 through protractor. I run the tests headless too albeit I don't do it via chromeoptions. Rather I run tests headless using xvfb-run on a unix distribution. I'm encountering this issue also albeit it fails randomly for me. See stack below

My code at the beginning of each test does the following

browser.manage().window().maximize();

changing to

driver.driver.manage().window().maximize();
driver.manage().window().maximize();

doesn't work for me either unfortunately. Shouldn't browser.manage().window().maximize() be still working as I'm running headless using xvfb-run rather than doing headless via chrome options?
