Playing in Borderless Windowed feels much worse than Fullscreen

From what I can see from my performance stats, the issue doesn’t seem to be frames or input lag, yet my aim and movement (wall riding especially) gets so much worse when I swap to borderless windowed.

Any ideas on a fix or what the issue could even be?

I have a recording of a comparison and screenshots of the ctrl shift n pop up if people need, i just cant link in the post
