So I updated windows the other day before getting in bed. Wake up, log in, everything goes normal until I click on something, and my mouse cursor just vanishes entirely. It functions; as in I can still click things where my mouse otherwise would be, but the pointer is completely invisible.

What's more strange is I don't have this issue in 4k, which is my monitor's native resolution. Even if I drop the monitor resolution to 1440p (what I play the game in normally), the mouse cursor is completely invisible unless I play in 4k.

None of this occurs in windowed borderless. only fullscreen, but prior to the windows update I had no issue with the mouse whatsoever. I updated my graphics driver to the latest, I have the latest mouse driver, pointer trails are off, dpi settings have been tinkered with. My only solution seemingly thus far if I want the game in fullscreen is to play in 4k. I certainly can... but I'd rather not sacrifice visuals. And of course I can also just play borderless... but I'd rather not.
