GTK Oddities in Pantheon

HI there, I am doing some testing with the Pantheon desktop, but generally use Gnome at this point.

When moving over to Pantheon (remove gnome) the window controls are tiny, and the windows are overlapped by the panel.

I am not 100% if this is a gtk issue (maybe theme or gtk setting related), or a Pantheon issue (hoping to hear from some of the other Pantheon users).

Has anyone run into this? Be it with or without Pantheon?

Thank you.
