This may be a very specific issue to me, but when using multiple desktops in Windows 10, if I switch back and forth from the one with my Unity Editor open, it partially switches my Editor Skin from personal to professional, but only if the Unity Hub is open. I'm running Unity Hub beta v.0.11.0, and I'm opening a project through it into Unity 2017.2.1f1. I have a Unity Pro license key, but my editor skin is set to personal. If I switch Windows 10 to a second desktop, then switch back, my Unity Editor has multiple parts showing the professional skin (but not all), and if I go into the Editor preferences, the skin is listed as professional. Switching back to personal works, but if I switch desktops again, the issue will reappear. Closing the Unity Hub application while leaving the Editor open solves the problem.
