Error: Command failed: xvfb-run --server-args="-screen 0 1280x720x24"

What is your Scenario?

Test runs in GitHub Actions should complete as normal - but quite often freeze, and fail. This happens with and without the testcafe-action. This behaviour seems to have started since the releases of 3.x.x and beyond

We've reduced concurrency, but still results in the same error/s

What is the Current behavior?

The error below occurs intermittently when running our Testcafe tests with GitHub Actions. There doesn't appear to be any set pattern, they can just fall over at any point during a test run with the error below.

Running headless doesn't resolve the issues - we've also experimented with and without the testcafe-action

This happens with our own self-hosted, as well as, GitHub hosted runners

The issue can appear if xvfb is not installed in your self-hosted runner, so it's hardly a TestCafe issue. As for testcafe-action, that package is deprecated, so we cannot give any recommendations on this.
