[Steve B. <st...@at...>]

This has made the lag completely go away and has fixed the caps lock issue!

Apple are catching the keypresses and trying to action them as well, I get this when I put caps on.



And I get this is I hold down key repeat (this is holding down O


, 

The caps thing happened before the fix, the repeat thing is new.

I don’t care about either, it's just interesting to note.

Thanks for the fix!

But the fix was wrong, it just looped over all events and noticed only the last pressed key. That explains the missing keys, you basically pressed two keys within one frame and the first one was thrown away.

The few that there were, were all due to missed characters and the few lines I had to retype as I was typing were also missed characters. That could be me, I am a part of the feedback loop after all, and I wonder if the sound was making it feel like something wasn’t going right and that was spoiling my rhythm so I would stumble.
