### Godot version

4.1 dev2, 4.0.3

### System information

Windows 10, ryzen 5900x, radeon 6950xt (driver: 23.2.2)

### Issue description

There are two bugs:
- When I create a new node, it is created outside of the viewport. (as in first video)
- When I run the project, all the content inside the viewport dont appear. (as in second video)
I believe the second issue is related to the first.

Note: these problems are in RTL editors.
