In short: first shop window not full screen and any mtx detailed window - full screen. Just why… make the even size, all fullscreen or all not full screen (full screen better btw, idk why you made shop window not fullscreen this is nonsense).
Small addition: “get points” button should be colored in different color, but please move it from top left (this should belong to “go back” button) to another spot. I know its sweetspot, but cmon navigation and elements positioning in shop right now sucks.
