I am currently using the Blackwidow Chroma V2 Keyboard and have been running into this issue lately that I have no clue on how to fix or what's causing the issue whether it be on the game's end, the keyboard, or Windows 10.
I noticed the issue after getting into Discord with a few guildmates in WoW. For some reason, if I turn my character with the A key while pressing Ctrl (Push to Talk in Discord), and then release both keys close to each other, my character will turn/strafe to the left without the A key being pressed. Even without Discord open I can replicate this by doing A key Press -> Ctrl Press -> A key release -> Ctrl release.
I thought it might simply be that the A key was sticking, however doing the previous motion in a search bar or text document does not result in a string of A's.
Also as a side not, ONLY the A key does this. Doing the motion with other movement keys does not produce the same effect.
