### Issue description

#79975 closed his issue too early, it's a separate issue to #78434.

I'll just repost his same gif:

### Steps to reproduce

I had a theory it was related to editor settings and I tracked it down:

1. Editor -> `Display Scale` = Custom
2. Editor -> `Custom Display Scale` = 1.15
3. Click Save & Restart
4. Print stuff

```
var number := 0
func _process(delta: float) -> void:
	number += 1
	print(number)
```

The scale number matters, 1.1 seems to be fine but smaller decimal places such as 1.15 are what cause the issue.
