Textual in docker containers #5231
Description
When running Textual apps in docker containers strange characters appear on screen.
Minimal Dockerfile to reproduce
FROM python:3.9-slim
RUN pip install textual textual-dev
COPY main.py main.py
CMD ["python3", "main.py"]
Where main.py contains
from textual.app import App
from textual.widgets import Button
class Test(App):
def compose(self):
yield Button("Hi")
if __name__ == "__main__":
Test().run()
When moving the mouse pointer over the terminal, numbers appear. They seem like screen coordinates.
