My bad, I should specify this. All the top bar buttons and everything disappears except the roblox icon button. But the toolbar it self still takes up space. https://gyazo.com/01cc40b0295f6a862487ededd4a4bd53
That’s probably intentional from ROBLOX’s behalf to prevent games that rely on the topbar offset from breaking. For now you can offset GuiObjects by -50 to place them at the top of the screen.
Use the IgnoreGuiInset property on ScreenGuis, this will increase the gui viewport size 36 (the topbar size) pixels to fill the topbar space, keep in mind the topbar will still render ontop of all your own objects
