Large files are unusable in the code editor

Likely something the react profiler will help fix because this feels like the main thread is getting blocked.

Notice the key spam but the cursor moves in jumps.

i fear this touches a few things

I highly doubt it is any of the codemirror code tho, or plugins since none of those changed in the electron port and now all of a sudden its doing this, which makes me lean towards react

If it's large files, my gut guess would be that we're maybe parsing the code on cursor moves when we should only do that on actual text change, and that's blocking the main thread.
