Cursor out of sync with screen in fullscreen, in-game chat not letting me delete certain amounts of characters

This problem doesn't happen in windowed mode, but in fullscreen mode the cursor doesn't line up with where I'm actually clicking, the image of the cursor is above where I'm actually pointing at. In the in game chat, I can delete some number of characters usually, but I get stuck at around 3 characters (so I can't use backspace to remove the first 3 letters I type). Any help?

Hey @GustavCuttlefish,

Thanks for bringing this to our attention. Can you upload your DxDiag here, please?
