I confirm the bug, as above, and that @jonafato 's patch fixes it for me. However, it's not the right fix. The problem is that ProgressBar is being used in the wrong way. This also results in two lines being printed instead of one, like this:

[#######-----------------------------] 20% [####################################] 100%% The bug is reproducible for me in any terminal, including Gnome Terminal and Guake, and VSCode. With VSCode I can use this launch.json to reproduce it:

```json

{ "version": "0.2.0", "configurations": [ { "name": "Python: Module", "type": "python", "request": "launch", "module": "sqlite_utils", "justMyCode": false, "args": ["insert", "test.db", "test", "--csv", "tests/sniff/example1.csv"] } ] } ```

[edit - deleted my analysis of why the current code is wrong, which was confused and confusing]

I think I see what is happening here, although I haven't quite work out a fix yet. Usually:

• click.progressbar.render_progress() renders the cursor invisible on each invocation (update of the bar)
• When the progress bar goes out of scope, the __exit()__ method is invoked, which calls render_finish() to make the cursor re-appear.

(See terminal escape sequences BEFORE_BAR and AFTER_BAR in click).

However the sqlite-utils utils.file_progress context manager wraps click.progressbar and yields an instance of a helper class:

python @contextlib.contextmanager def file_progress(file, silent=False, **kwargs): ... with click.progressbar(length=file_length, **kwargs) as bar: yield UpdateWrapper(file, bar.update)

The yielded UpdateWrapper goes out of scope quickly and click.progressbar.__exit__() is called. The cursor is made un-invisible. Hoewever bar is still live and so when the caller iterates on the yielded wrapper this invokes the bar's update method, calling render_progress(), each time printing the "make cursor invisible" escape code. The progressbar.__exit__ function is not called again, so the cursor doesn't re-appear.

When I run reset it fixes my terminal. I suspect it is related to the progress bar
