I found some behavior in my own Godot 4 game which is easy to reproduce:

  1. Open Godot 4.1, I'm using Windows 10, 64bit
  2. Create a new project, I called it OrphanStringTest001
  3. Add a scene with an empty Control node
  4. Run once to make that scene the default
  5. Export the project for "Windows Desktop (Runnable)" with all default options, choose "Export Project..."
  6. Disable "Export With Debug" checkbox (this step is crucial)
  7. Run from your terminal with an argument: .\OrphanStringTest001.exe --verbose

After closing the app:

  • Result: tons of Orphan Stringname: ... messages
  • Expected: clean exit without any such warnings

Here's the full log (abbreviated the list of "Orphan" messages though), first on startup:

And after exiting the "game" it adds:

Orphan StringName: KEY_PERCENT
Orphan StringName: Key
Orphan StringName: KEY_BRACELEFT
Orphan StringName: PROPERTY_HINT_PLACEHOLDER_TEXT
StringName: 658 unclaimed string names at exit.

This seems like a problem, and my "real" game has nearly 4000 of those "unclaimed string names" at exit. Then again, since this happens in an empty project with default settings, it might just be "normal" and expected behavior?

My questions: what do these log messages mean, should I worry about them, and if so, how should I fix this?

The issue you're describing can be found on the Godot GitHub here, created February 2023 and still open per the time of asking your question. It seems like it is a regression in the engine that is still being investigated. I wouldn't worry for now unless you are exporting your games with a console, where the amount of text dumped may lengthen your shutdown time considerably.

  • \$\begingroup\$ Thanks! This is a proper answer, at least at this point in time, I think. I thought I had major memory leaks that I needed to take care of, but it seems I have memory leaks I don't need to take care of for now 😅 - good to know it's just this. \$\endgroup\$
