There is no option in the game for it :(( at least i looked for it and it wasnt there (and idk where i could change that directly on my pc knowing its already borderless so i dont have access the usual close/reduce buttons)

There should be a tick box in the visuals somewhere to switch it from normal fullscreen to borderless. Now that you mention it, there may not be a windowed mode, and I remembered that wrong. I apologize for that. If you already tried the tick box, though, I would say make sure your resolution is set correctly. Or -- in games that have done this to me before -- try resetting from fullscreen to borderless, or the other way around and see if that improves at all.
