Made an account here so I could throw my hat in the ring. My husband got this keyboard for me for Christmas, and it has been giving me issues ever since. I've been trying to roll with it, it was a nice gift and the keyboard is pleasant to use, but this ghost writing issue needs to get fixed. We are well past the return window unfortunately, so we can't get our money back, but it is affecting our willingness to buy from Corsair in the future.
Sometimes it happens before I even log into windows, sometimes mid-session, unplugging and plugging back in fixes it temporarily. I actually went a week or so with no instances, but this week we're back at it happening at least once a day.
