Help why is my game doing this

Amyalicia13​  Are you using any overlays that might be affecting the game?  That could be ReShade or GShade, or GeForce Experience or the Nvidia App applying an overlay, or another third-party app.

And does this happen if you put the game into windowed mode?

Please also provide a dxdiag, for reference.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
