Extension plugins scaling

Hi, I have a problem with scaling of the extension plugins like SpectraLayers or Melodyne

A you can see, there is a blank space on the right side of the window. And that’s actually the better case, sometimes I got blank space on the bottom as well, making it really weird to have a fullscreen window and only like a 3/4 of it filled with the plugin. Resizing the window resizes the plugin as well, with the blank space too. As it was a part of that plugin. Will you help please?

I have no idea what I’ve just done, just closed the plugin and opened again, but it’s even worse.
