If you're on windows, I've done this with a few apps. Just change your screen scaling in windows (win button, settings, display) to 100% or smaller. It will make you log back in. Open studio one, shrink its height and close it. Than change the screen scaling back to where you had it and log back in. The whole thing should fit and then you can resize it how you want. Or if you just want to maximize it press alt+space, then press x.
