What do you think about solving this by giving the user the ability to manually increase or decrease the subtitle size on the fly, similar to how VLC Media Player handles it?

Instead of relying entirely on the automatic scaling (which seems to be causing this inconsistency between Full Window and Full Screen), we could add a keyboard shortcut (e.g., Shift + + / -) that allows the user to adjust the size to their preference regardless of the window mode.

If you think this is a feasible approach and fits the project's direction, I would be more than happy to work on implementing this feature myself.
