How Can I change WebGL information?

[damidoug]

When we test on https://pixelscan.net/, the WebGL information matches that of my computer. Is there a way to insert random information? It's as if we could introduce a method to randomize hardware details, the operating system (Windows, Linux, Mac, etc.), screen resolution, and more.

Yes, that's been done before. Even before UC Mode existed, there was an integration with selenium-stealth (#942 (comment)), which lets you "change" (fake) various properties:

You can integrate it directly into the custom setUp() method of your tests like this after you pip install it:

from seleniumbase import BaseCase
from selenium_stealth import stealth

class BaseTestCase(BaseCase):
    def setUp(self):
        super().setUp()
        stealth(self.driver,
            languages=["en-US", "en"],
            vendor="Google Inc.",
            platform="Win32",
            webgl_vendor="Intel Inc.",
            renderer="Intel Iris OpenGL Engine",
            fix_hairline=True,
        )

Then have your test classes inherit BaseTestCase instead of BaseCase. (See SeleniumBase/help_docs/syntax_formats.md#sb_sf_02)

There's general information on StackOverflow about that here: https://stackoverflow.com/q/70265306/7058266

Additionally, you could use driver.execute_cdp_cmd() to make internal modifications to your Chrome settings.
You would need to be familiar with CDP internals: https://chromedevtools.github.io/devtools-protocol/tot/Network/.
For example, here's a SeleniumBase script that changes your GeoLocation: SeleniumBase/examples/test_geolocation.py

I tried your codes, but error. WebGL never queried/empty.
