Headless Browser in Chrome 137 suddenly stopped maximising or windows size is not set 1920*1080. Below is my robot keyword. Does any one face this issue when running headless with latest chromedriver. Any help much appreciated please?

Hi, I’ve had this problem for a couple of weeks now.
Chrome update broke headless, all chrome driver options failed for me, tried many, including ones in your code.
If no one has a solution, I’m afraid we’ll have to wait for bugfix by Google. :frowning:
For reference, here’s a link I found today: [🐛 Bug]: ChromeDriver not honoring the --window-size parameter · Issue #15827 · SeleniumHQ/selenium · GitHub
