### Godot version

4.0.beta.11

### System information

windos10

### Issue description

Just touch 'godot' and make a demo while learning.
After `beta. 11` was released, I tested my Demo on the new version, and it flashed back frequently without any sign. I searched for a long time and didn't find the reason.




### Steps to reproduce

This code runs normally from `beta.5` to `beta.10`, and flashes back frequently and irregularly on `beta.11`.
