Ardour informs LV2 and VST3 plugins about Ardour's UI scale (Ardour Preferences > Appearance > Size and Scale).
It's up to the plugin to render at the correct scale. There's nothing Ardour can do about this.

I suggest to contact LSP's dev (SadKo)

Worked fine in previous versions though

Are you perhaps using Wayland and Xwayland desktop scaling instead of Ardour's UI scaling?

Which previous version of Ardour and LSP do you refer to?

On Wayland but I've no idea what scaling method is being employed.
I recall it working fine in 8.12 and possibly earlier 9.x versions. I am not certain of LSP versions. Go ahead and close this as I think I'm not really certain of the details, sorry
