Unity Cursor.LockState bug?

I'm using Unity 2019.4.9f1 for the first time, and I've run into a really annoying problem. When I set Cursor.LockState = CursorLockMode.Locked, it no longer locks my mouse to the center of the game window but a bit below it. This means that if I'm using anything triggered by a click, I end up clicking out of the game view and defocusing it. This is making my game extremely difficult to playtest. I have moved the play window around and tried setting maximize on play but the cursor never centered. It seems like it is set to lock to a position somewhere below center. I checked in an earlier version of Unity and everything was fine, so is this just an error in this release? I also tried using CursorLockMode.Confined to see if that was working, and it confined me to an area the same size as the play view, but again shifted down by about 50%. Is there anything I can do about this, aside from saving everything as a .unitypackage and importing it into an earlier version of Unity? I'd greatly appreciate any help!
