In investigating openQA test results, I've noticed the anaconda webui frequently has issues with inconsistent rendering of interface elements. This causes tests to fail frequently. We paper over this to some extent with the 'automatic retries' system in openQA: all update tests are retried once, and we currently have the install_default_upload test configured to retry 5 times, which is hiding this problem on that important test. But you can really observe it with the install_webui_ext4 and install_webui_xfs tests, which frequently show up as failed. And you can look at the history of the install_default_upload test, which shows it frequently failing and needing to be retried: https://openqa.fedoraproject.org/tests/3844621#next_previous If we look at some of the failures, the classic issue is a button being a darker blue than it is supposed to be - the "Next" button here: https://openqa.fedoraproject.org/tests/3844357#step/disk_guided_empty/7 But there's also a fairly common failure mode where the UI comes up with the wrong font: https://openqa.fedoraproject.org/tests/3824036#step/_boot_to_anaconda/8 There are also issues with webui apparently crashing or being unresponsive on startup, but I'll look into those separately. I'm bumping the RAM in openQA tests to 4G in the hopes it will help with overall reliability of these tests especially, but it still feels worth reporting the problem.
There's also https://openqa.stg.fedoraproject.org/tests/5477504 , where a page that should have some bolded text on it has none, like we just somehow failed to apply text styling.
