After persisting with it for over a week, I had to revert back to Sublime. The typing experience of native is still just so much better.
I'm very sensitive to issues like that and I find it buttery smooth. Though I am running it on a rather highly performance system.
The specific issue that became my last straw was automatic insertions of return char. I think linked to the intellisense plugin. But I just lost patience and went back to a reliable text editor.
Remember, vscode extensions are written by third parties and not always very well-written.
