Do you have a link to the file? What line are you editing and becoming slow?

every line.

Did you try by disabling all the packages, also which syntax highlighting are you using?

I dont see a noticeable lag, but is also not as smooth.

The same, very slow for large JS files. Syntax - JavaScript, no lag with Plain Text or with un unsaved buffer. In particular, problems when scrolling @finscn file above. I actually noticed that on my smaller .js file, only about 470kB. MacOS Mojave 10.14.6, Sublime Text Build 3211. It didn't take place on High Sierra (updated to Mojave only recently).

Do you guys have the TypeScript package installed? It was the culprit for me.

• large line file move cursor slow but copy to new not slow. when I watch jquery #3203 (comment)
• Plugin slows down Sublime Text microsoft/TypeScript-Sublime-Plugin#716

Or you guys just do a plugin profiling by yourself to find possible culprit(s).
Tools -> Developer... -> Profile Plugins...

[gibbopotam]

I just reinstalled Sublime Text, the problems persist. As a workaround, with Plain Text being too dull, I use Syntax -> C. Some other syntaxes do also lag for me. @jfcherng: I didn't install TypeScript package, but installed Dart package some time ago and still see it active.

[jfcherng]

do a plugin profiling anyway. if you didn't revert ST to its clean state, re-installation basically does nothing.

[gibbopotam]

@jfcherng Thanks, it worked! Uninstalling Dart plugin didn't help, but I then uninstalled TypeScript plugin (probably existed by default for I didn't install it), and now I use Syntax -> JavaScript and it's fast. Thanks again.

@finscn can you reproduce this issue from your initial report with a reverted profile?

[jfcherng]

@gibbopotam @MauroSequenzia btw, if you still need typescript syntax highlight, you can use https://packagecontrol.io/packages/TypeScript%20Syntax
