@stryker313 The minimal reproduction project failed to upload, please try again.

Also, remember you may be encountering https://github.com/godotengine/godot/issues/55145. As a workaround, try to run the project twice.

Not sure what you are expecting, but this works correctly: What you set in viewport width/height is used as a default reference size, so changing it has no effect on scaling. What you are looking for is window width/height override, which is hidden under Advanced Settings.

Needs to be better documented then, I expect many new users will run into this.

This is explained here: https://docs.godotengine.org/en/latest/tutorials/rendering/multiple_resolutions.html#stretch-mode These properties were renamed for better clarity.

It's not made clear enough in https://docs.godotengine.org/en/latest/tutorials/rendering/viewports.html, though. Scale and stretching aren't clarified enough, nor is the meaning of 'size' made clear in the API docs https://docs.godotengine.org/en/latest/classes/class_subviewport.html#class-subviewport

Please open an issue for this on the godot-docs repository (and ideally a pull request for the Viewports page :slightly_smiling_face:). For the SubViewport class reference, edit https://github.com/godotengine/godot/blob/master/doc/classes/SubViewport.xml on the main Godot repository and open a pull request.
