* Firstly, may I ask are you using Vim extension?
* Can you please follow instructions listed here https://github.com/microsoft/vscode/wiki/Performance-Issues#... to profile the renderer process when that happens (more accurately start the profile before the hang happens and stop after). Usually extension should not block the typing so it might be something bad in the core. Once you have it captured, please file an issue
VSCode member here. Did you use the Vim emulator all the time, especially when you feel typing is slow? It would be awesome if you can provide more info in https://github.com/Microsoft/vscode/issues and we'd love to fix the problem. Laggy typing/navigating is always a high-priority bug to fix.
The reason that plugin lags is because it was using `setInterval` initially but I changed it to selectionChange hook and now it works smoothly. Now the only problem with it is it hides breakpoints but definitely we will improve this experience later on. / I'm a Code team member*/
Thanks in advance for the help.
