### Apache Airflow version 3.1.2 ### If "Other Airflow 2/3 version" selected, which one? _No response_ ### What happened? When logging a relatively small amount of data (in this example, JSON records) then UI logs seem to have visual issues after about 50 lines <img width="1083" height="499" alt="Image" src="https://github.com/user-attachments/assets/c2b68de6-df1f-442b-a868-b2bc22e42526" /> https://youtu.be/s7kJTNeSjHQ ^^ Video of the observed behaviour. This has been introduced somewhere between 3.0.6 and 3.1.2 which we upgraded to this week. NOTE: The logs are downloadable from the UI and we are using remote logging to S3 for task logs, but this appears to be a front-end issue so that SHOULDNT matter ### What you think should happen instead? The logs should be readable from the UI. ### How to reproduce Tiny reproducible setup used for the Youtube video above [json_logging_test.py](https://github.com/user-attachments/files/23496314/json_logging_test.py) Run this in airflow -- we personally see the output start to "freak out" in every single task, but it gets worse as the number of lines printed progresses. Past 200 its completley invisible. ### Operating System MacOS ### Versions of Apache Airflow Providers default providers for 3.1.2 ### Deployment Official Apache Airflow Helm Chart ### Deployment details EKS ### Anything else? _No response_ ### 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.
