My mouse cursor visually lags behind where it should be on my screen,
this happens almost every time a game is open, but most noticably in games that make use of the default Windows 11 cursor in some way, rather than rendering their own cursor.
It feels as if the cursor I'm being shown on my screen is chasing the real cursor, which is somehow hidden.
I recorded a video of this issue occuring, and I captured it behaving exactly as I expected:
Firstly, my screen gains a yellow-ish border for around 1/4 of a second, followed by a lag spike, then my cursor's weird behaviour starts.
In the video I recorded, it captured a second cursor that didn't appear on my main monitor, and I'm very confident this is the actual cursor that I should be seeing.
I am now 100% sure that this is a rendering/software related issue, I see no possibility for this to be a hardware issue, at-least in relation to peripherals such as my mouse.
Things I have tried, without any notable success:
Testing with different applications open (certain ones seem to trigger slower than others).
Disabling Windows 11's "Animation effects" feature.
Disabling Windows 11's "Scroll inactive windows" feature.
Ensuring that any unwanted mouse settings weren't enabled (cursor trails, mouse acceleration).
Disabling my primary monitor's HDR mode.
Lowering both of my monitors refresh rates to match the lowest one.
Disabling all power saving features on my mouse USB busses.
Updating my mouse's drivers.
Doing a complete fresh re-install of my graphics drivers using the NVidia GeForce Experience app.
And other minor things I cannot think of right now.
