Steps to reproduce

activate mouse crosshairs and move the mouse

The crosshair is responsive to mouse movements.

❌ Actual Behavior

For me, it’s

always the case when using my physical mouse
sometimes the case when using my trackpad (see also #24096)
always the case when using Mouse Keys (Accessibility ➡ Mouse) [tested this for science]

Crosshairs are very "choppy" as I move around my pc and give me an illusion that my pc is somewhat lagging while my mouse still moves smoothly. Can we sync it with monitor refresh rate?

I had a pretty detailed description of this behavior in https://github.com/microsoft/PowerToys/issues/16650. Despite some comments here and there stating that this issue is unrelated, what I was reporting was actually due to two different things working together: the crosshair thickness issue (a static offset), which was solved; and this delayed update issue (a dynamic offset), which remains overlooked.

Is there any reason the code from the screen ruler tool can't be reused here? It seems to work perfectly as far as I can tell.
