# Bug report

### Bug description:

```python
import time

print('hello', flush=False)
time.sleep(10)
print('world')
```

Before sleep:


After sleep:


This causes flickering when displaying text in a CLI, which is how I discovered this.

New signature, backwards compatible (if you didn't use the default argument `flush=False`):

```python
@overload
def print(
    *values: object,
    sep: str | None = " ",
    end: str | None = "\n",
 file: _SupportsWriteAndFlush[str] | None = None,
    flush: Literal[True] | None = None
) -> None: ...

@overload
def print(
    *values: object,
 sep: str | None = " ",
    end: str | None = "\n",
    file: SupportsWrite[str] | None = None,
    flush: Literal[False]
) -> None: ...
```
