codecae opened a new issue, #35301: URL: https://github.com/apache/airflow/issues/35301
### Apache Airflow version 2.7.2 ### What happened When rendering task-to-task dependencies between tasks that are buried into nested task groups, the UI tends to draw the relationships and node spacing in unusual ways. <img width="723" alt="image" src="https://github.com/apache/airflow/assets/8164265/ad86c0cc-7bbb-496c-a80a-a1dadb6a8c4e";> ### What you think should happen instead The UI should render the graph consistently, regardless of what level you have drilled into the task groups. ### How to reproduce Run this test code to reproduce the issue: ``` from airflow.decorators import dag, task, task_group import pendulum from typing import List, Dict from airflow.models.baseoperator import BaseOperator _all_tasks: Dict[str, List[BaseOperator]]={} @dag( schedule=None, start_date=pendulum.datetime(2023,1,1), ) def test_dag(): def _generate_task_group_callable(group_id, tasks): @task_group(group_id=group_id) def _task_group(): [t() for t in tasks] return _task_group def _generate_task_callable(task_id, task_set): def _generate(): @task(task_id=task_id) def _task(): pass if _all_tasks.get(task_set, None) == None: _all_tasks[task_set]=list() _all_tasks[task_set].append(_task()) return _generate _set_callables=list() for _set in range(0,2): _set_id=f"set_{_set}" _group_callables_a=list() for _nga in range(0,3): _nga_id=f"group_{_nga}" _group_callables_b=list() for _ngb in range(0,5): _ngb_id=f"group_{_ngb}" _task_callables=list() for _task in range(0,10): _task_id=f"task_{_task}" _callable=_generate_task_callable(_task_id, _set_id) _task_callables.append(_callable) _group_callable_inner=_generate_task_group_callable(_ngb_id,_task_callables) _group_callables_b.append(_group_callable_inner) _group_callable_outer=_generate_task_group_callable(_nga_id, _group_callables_b) _group_callables_a.append(_group_callable_outer) _set_callable=_generate_task_group_callable(_set_id, _group_callables_a) _set_callables.append(_set_callable) [_s() for _s in _set_callables] for i in range(0,len(_all_tasks['set_0'])): _all_tasks['set_0'][i] >> _all_tasks['set_1'][i] test_dag() ``` ### Operating System Debian GNU/Linux 11 (bullseye) -- apache/airflow:slim-2.7.2-python3.10 container ### Versions of Apache Airflow Providers apache-airflow-providers-common-sql==1.7.2 apache-airflow-providers-ftp==3.5.2 apache-airflow-providers-hashicorp==3.5.0 apache-airflow-providers-http==4.5.2 apache-airflow-providers-imap==3.3.2 apache-airflow-providers-sqlite==3.4.3 ### Deployment Docker-Compose ### Deployment details _No response_ ### Anything else if the grid is is filtered, it has been observed that the graph renders properly in some scenarios. Doing task-group-to-task-group relationships sometimes renders properly, as well. ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
