Hyper key causing keyboard input lag - workaround?

After a repeatedly miserable experience with keyboard input lag, I found a few threads online that seem to point that it could be the use of my hyper key as caps lock. Now having turned it off it looks to have solved it.

Quite devastating that it is buggy or something about my setup doesn’t like the hyper key. Could you recommend an alternate key combo which doesn’t clash with app shortcuts?
