Black region after startup

[lolpowerluke]

I have 3 monitors:
2 2560x1440 monitors without transform set and 1 1920x1080 monitor with transform 1, all have scale not set

when starting hyprland, I sometimes have part of my monitor be black

this img is taken on one of the 2 2560x1440 monitors, but it also happens on the 1920x1080 monitor, there its just at the bottom instead of the side

this problem started after I added the 1920x1080 monitor, and looking at the size of the region that isnt black
if it happens on the 1440p monitors, it has the width of the 1080p monitor and if it happens on the 1080p monitor it has the height of the 1440p monitors

hyprland version is 0.50.1-1 (latest at the time of writing)
Distro: Arch linux

lmk if I need to provide more info
