Mouse sensitivity increases while playing videos (Only in GNOME)

I’m using GNOME as my DE for it’s customization , and on a fresh install, even in the live USB, if I have mouse acceleration turned off in Tweaks, most noticeably while I’m playing a video, through Youtube or otherwise, the sensitivity will go up (or the acceleration turns back on, I’m not sure which). Does anybody know why this is? (I’ve tried Googling around for about half an hour now)
