Wallpaper & waybar scrolling with the windows when changing workspaces

[NikoPit]

When you change a workspace, the wallpaper and waybar scrolls with the window.
Only the windows should scroll up/down, not the waybar / wallpapers

This is not an issue, and is intended

To fix this, set waybar to the top level and follow this below for wallpaper
