Resolved Constantly looking down in WebGL

Not sure if this is a bug, or if I'm doing something wrong as this is my first WebGL game.

I have very basic first person movement controls, they work fine in the editor but when I build my scene the camera is constantly rotating down. I can fight it by sliding the mouse up(or add to it by sliding the mouse down), but I can't figure out what's causing it.

I can't seem to find anyone else with this problem, but this feels like a glitch. Any thoughts?

Here's my code, just in case:

Code (CSharp):

1. public Transform playerBody;
2.     public float xSpeed = 100f;
3.     public float ySpeed = 100f;
4.     public bool invxAxis = false;
5.  
6.     private float yRotation = 0.0f;
7.     private float xRotation = 0.0f;
8.  
9.     void Start()
10.     {
11.  
12.         Cursor.lockState = CursorLockMode.Locked;
13.  
14.     }
15.  
16.     void Update()
17.     {
18.  
19.         float mouseY = Input.GetAxis("Mouse Y") * xSpeed * Time.deltaTime;
20.         float mouseX = Input.GetAxis("Mouse X") * ySpeed * Time.deltaTime;
21.  
22.         if (invxAxis == true)
23.         {
24.             xRotation += mouseY;
25.         }
26.         else
27.         {
28.             xRotation -= mouseY;
29.         }
30.  
31.         yRotation += mouseX;
32.  
33.         xRotation = Mathf.Clamp(xRotation, -80f, 80f);
34.  
35.         //yRotation += mouseX;
36.  
37.         playerBody.localRotation = Quaternion.Euler(xRotation, yRotation, 0f);
38.  
39.     }
40. }

 

Update: the problem seems to have solved itself.

Since there was nothing wrong with the version in the engine itself, I moved on until I could get help from here. recently -- despite not working on any of the scripts involving camera movement -- my builds have stopped giving me this issue. Fingers crossed it doesn't come back, but if this was an issue with WebGL or chrome, it seems to have been solved on their end.
