Komorebi leaving a margin at the top of the wallpaper

[Rupioe]

Hello, im running arch with i3 and when im running komorebi, my whole 1920x1080 screen isnt totally covered on the top despite the fact that my custom image wallpaper is 1920x1080, all of the default wallpapers are not filling my screen too. It could make no difference if my bar was covering the hole but it isnt. Where can I fix this ?
