Controls acting up

So sometime when I enter a mystery hero match my cotrols are acting up. There’s nothing wrong with my keyboard but it’s like suddenly my character starts to walk sideways without me pressing A or D. Sometimes my character walks even if I stop pressing my buttons. It stops after a while when I let go of the keys. It could be my keyboard but the problem is only in Overwatch.

Are your keys sticking at all?

My keys work just fine in all other content and when I write and stuff. The weird part is sometimes my character insist on strafing or even walking backwards even though I’ve not touched those keys. It just started happening tonight and over 2 Mystery hero maches.

Bump.
Same issue. Blizz Please address.

And now my mouse is acting up and primary fire not working while I move my character.
