I love the design and colours of this theme, but unfortunately it causes the window to randomly shrink by it's own accord. I think there is some sort of resizing bug with the theme and it's been reported by multiple people:

New version 1.6. Thank you very much for reporting it, we have resumed working on the issue and fixed it, it no longer presents the error of resizing the window, thank you for your support.
