Is there a foolproof way of testing mouse and monitor latency/refresh rate on linux? (programming.dev)

I could swear that my mouse is lagging on my second monitor but I don't how how to actually "prove" it, if there's even a way. I am dual booting windows with fedora workstation gnome and there is a noticeable sluggishness to my mouse control whenever I switch back and forth, but only on the secondary monitor. It is slight but it's messing with my muscle memory and constantly making me overshoot clicks and buttons. The main display seems to be fine, or at least it's less pronounced due to higher monitor refresh rate.

Is there any way I can measure it objectively and find the root cause? A diagnostic tool or an app that could test if something is wrong? It's a recent fedora installation and I've gone through all the nvidia driver and media setup steps at this fedora post-install guide but honestly I don't even know if this is a fedora, gnome, driver or wayland issue (or something else completely)
