Brief description of the issue:

the “three separate main screens” (welcome/profile/options) are not separate screens on “ultra” wide resolutions like 2560x1080 or 5120x1440. Instead, you can see parts of the other menus, and as such you fully expect to be able to click them or use left/right to navigate to them. Instead, it’s just inert content until you first change the screen by changing the screen heading at the top, which is rather silly.
