Manual test run on Linux x64 for 1.69.x - Nightly (Checking C127)

Using the following combination of Linux versions and configurations, ensure that you can load several websites without any issues using a build running C127. For example, ensure that the page actually loads and doesn't have any obvious/visible artifacts. Some context: try avoiding shipping Linux with issues like https://github.com/brave/brave-browser/issues/31947.
