#iTerm2 / #fish shell users, what is this awful iTerm2 feature and how do I kill it with fire? I just upgraded my fish shell and now I get this junk in iterm2 and I don't know even what the popup feature is _called_ much less how to kill it.

Apparently #macOS 26 has a bug that leads to massive CPU usage and lagginess in apps until you terminate and restart them. The lagginess creeps in over time, until the affected app is restarted again.

I ran into this with #iTerm2 but the issue has been reported already months ago in macOS betas with various apps.

Workaround is to: defaults write -g NSAutoFillHeuristicControllerEnabled -bool false

You will lose some autofill functionality by doing this, but apps slowing down over time is quite annoying, too.

#Apple quality control leaves things to be desired yet again.
