Hello. I just bought a new keyboard(marvo k632) and i encountered a pretty strange problem, if i press more than 1 key, even 2, the keyboard doesn't send the signal to the mobo fluently, it sends the signal of the last key that is being still pressed in a flickery style, i'm sorry for my english but this problem is pretty strange and i don't know how to describe it, i think it might be ghosting but it says that the keyboard has anti-ghosting 26 keys. https://www.youtube.com/watch?v=5Syg9-gQowU Here is the video from which i think you might understand what kind of problem i have.
