IntelliJ: Thats your problem.

Everytime i tried to run their IDE's on mac os i gave up because the abysmal typing/scroll performance.

I think textmate broke my brain back in the day, can't stand any editor that can't run at 60fps. (unless it's vim/nano on ssh)

Hmmm.. I run IntellJ IDEA on my 2013 MBP and I don't experience system-wide text-entry latency. Though, to be fair my version of IDEA is pretty old (2016.2)
