Why does my camera get stuck scrolling?

This is a frequent glitch that happens to me. I will be scrolling by using WASD and then my camera will get stuck and keep scrolling. The only way I have found to fix this is spamming the WASD keys or toggling the pause menu repeatedly.

This also happens when controlling vehicles. I will be using WASD in direct control, and the vehicle will continue to move in the same direction without my input. Toggling direct control off fixes this. I don't think this should be happening, and I'm not sure if it's my hardware or the game freaking out. I don't have this problem with any other game, so I don't think my keyboard is ghosting.

How do I prevent my camera and direct control of vehicles from glitching?
