Description
What happened?
We've migrated from Ubuntu 20.04 to Ubuntu 24.04, and suddenly our Selenium screenshot sizes changed.
It seems that the initial window size now includes the search bar / bookmarks bar (and potentially other elements like notification bars), therefore the actual space left for the page content is smaller than the specified window size, even in headless mode. (Tried both the old and new headless modes, the results are the same.)
While the window size is 1800x900 pixels as specified (and as returned by get_window_size), the actual screenshot size is only 1800x708 pixels. Occasionally (for some tests) we also observed widths that were different from the originally specified widths.
It does seem like this might be an issue with Chrome / ChromeDriver, but I wanted to open an issue here as well to see if there's maybe something we can do as a workaround in the meantime.
How can we reproduce the issue?
