Hi, I have this strange issue when on alt tabbing only some keys will register. This happens across applications. I will alt tab out of a game and back in, and find only W works along side a few other keys, but no other key presses. Sometimes I can try alt tabbing out and in a few times and it'll fix it, and other times I have to restart to fix it.
Side note: I believe this started around the sort of time I mashed a bunch of keys, and wondered if I triggered some sort of equivalent to sticky keys. I haven't found anything relevant in the keyboard settings that has helped. I could be missing something or could be just coincidental timing. Thanks!
