I've tested your new firmware and made one good video with very systematic keypresses.

First of all. Sadly not one single option cured the problem, I tried altering both values (first, subsequent) in a systematic way starting with the lowest possible.

So I typed "OPTION RESET" and made this video with my wife as camera director; there is no difference to the official release, just in case you wondering if this version is a bit better (sadly it is the same - at least the result is)

So what are you seeing in the video?

Off camera, I already tested both keyboards and this pattern came out.

UPPER CASE: what I actually typed

lower case: what the result is

Now I am typing live on camera to show that this pattern is perfectly repeatable. Only in one case it differs (I am only human, sure it was me).

I tried to always keep the same speed. In case you wondering if I do this a little bit slower, it is also behaving like this. I am in the editor, but in the console it is the same.

I am moving forwards on the keyboard in a systematic way:

QWERT WERT ERTZ RTZU etc...

Video uploaded to my Dropbox :


As you can see both keyboards acting a little bit different, but I think there is a pattern... I really hope that this somehow helps. But it clearly shows that there is something wrong... If you have ideas, I will do more testing.
