annoying blank space under the mixconsole

this has been driving me crazy for a long time, numerous updates came out without fixing or addressing the GUI issues. The mixconsole randomly (from project to project) gets a big blank empty space below the mixer, regardless of the window size. Pictures attached.

Is this fixable in any way?
