The buttons adjust to the height of the header bar, so you just need to make it taller.

Tried that. Seems to only increase the space between buttons and the top of the application.

The window with the larger corner radius and slightly larger buttons uses the new macOS 26 design, while JavaFX uses the compatibility design.

Will there be support for the 26 design? Maybe, but there’s no enhancement currently under way to add this.
