Options().add_argument('--window-size=X,X') stopped working since 3.4.5; Last working version 3.4.4

[danielrzad]

Hi!
I just want to inform that Options().add_argument('--window-size=X,X') stopped working since version 3.4.5 (also not working in 3.4.6). Last working version is 3.4.4. I had hard time today debugging this so I'm posting this just in case someone else would be able to avoid those troubles.

I encountered the same problem....
and further more, i print all arguments out:

['--no-first-run --no-service-autorun --password-store=basic --no-default-browser-check --window-size=1200, 800', '--proxy-server=127.0.0.1:2226', '--proxy-bypass-list=<-loopback>', '--remote-debugging-host=127.0.0.1', '--remote-debugging-port=2230', '--user-data-dir=C:\Users\achil\AppData\Local\Temp\tmpa06lg9u0', '--lang=zh-CN', '--no-default-browser-check', '--no-first-run', '--no-sandbox', '--test-type', '--window-size=1920,1080', '--start-maximized', '--no-sandbox', '--log-level=0']

I found only the bold part is from my script, others from -proxy-server=127.0.0.1:2226 are not ....

At undetected_chromedriver/init.py#L379, undetected-chromedriver adds some arguments by default:/

I also encountered this issue, is there any solution? Rolling back to 3.4.4 also requires an older version of the browser, which is not what I want.

I have find a solution.
use Xvfb and pyvirtualdisplay
don't use headless
for the more question, ask chatgpt

brws.get("https://wikipedia.org")
brws.set_window_size(1220,2600)
