The wanted action
- Please delegate this task to a suitable developer
- Fix the autotest flakiness in all affected versions, not just one.
- Cherry-pick the fix to all relevant branches
- Mark the fix versions to Jira
- Try to fix the actual issue instead of just blacklisting the test function
Guidelines for debugging
Please see the internal page https://intranet.qt.io/display/QTRD/Metrics+Guidelines+for+Grafana+Tool+for+Autotests+with+Issues
