I have this issue with my 88 as well, but it doesn't seem as bad as yours.
I've been using a Yamaha KX88 for so long that I thought my technique was bad, so I've been practicing more piano music. So far, it has not helped. Korg Customer Service in USA hasn't heard of this issue, and your post is the first here that note it (this is NOT the same issue as the other thread).
I do know that playing Ivory or any other external MIDI device from the Kronos 88 doesn't have this problem, and playing the Kronos from my KX88 does not have this issue either. This also seems to be worse in the lower half of the keyboard.
My next step is to make a video for Korg Customer Support USA, which they requested.
I'll report back if they say anything.

2 days ago I purchased a Kronos 88 keys (one of the first delivered in Italy) and I immediately noticed a problem on RH3 keyboard, in fact, with a particular key is pressed, the sound was broken, almost stopped. Playing with energy, by pressing the keys hard enough, but the problem did not show up playing the hand dropping from a height (soft sound), from time to time, some notes were blocked shots.
Another person, also in Italy, found the same problem.
The shopkeeper gave me back the full amount of money and now are waiting on what to do.
I would like to know if any of you have found the same problem only affects some keyboards or delivered in Italy
Here you can listen to a recording of the problem
