Movement bugged ?

[LeBlackMeow]

I have a azerty layout keyboard, and I had to rebind some movement key. Like W to Z and A to Q. But sometimes, my forward movement (Z) get "stuck", like moving forward non-stop and sometimes it just doesn't move forward, like if the key doesn't work at all...

I have the same thing and I don't know how to solve it
