python + selenium: save_screenshot/get_screenshot_as_png crashes

[HongX Shi]

Hi Guys

with latest several weeks, whenever we run above functions in Chrome testing, it would get crashed periodically, and once it happens

- it tries to open more chrome browsers till out-of-memory

- it will go very slow for case play

- no snapshots for sure

notes:

1) it works well before

2) it only fail within chrome, not within Edge or Firefox

here is typical exception

Message: timeout: Timed out receiving message from renderer: 10.000

  (Session info: chrome=88.0.4324.190)

any solutions for this case?

thanks
