Does it happen in safe mode?

Seeing intermittent CPU spiking on 4107 on MacOS 10.13.6 as well when running Sublime Text.app. Looks like there are sublime_text sub-processes spawning, chewing up CPU and then dying. Running /Applications/Sublime\ Text.app/Contents/MacOS/sublime_text from the terminal seems to fix the issue.
