Not sure if this is related to Electron or not, but in VS Code I have issues with using the high key repeat that I have set on all my machines. If I try to hold down a key that navigates the cursor (arrow keys, delete, hjkl in Vim mode, etc.), the editor isn't able to move the cursor fast enough to keep up with the key input events, so it keeps moving after I've lifted the key for a bit. This is especially annoying when I'm trying to delete some text and end up deleting more than I meant to.

Obviously this is a super niche thing, and you could make the argument that there are more efficient ways to edit text than this. My main point is that I never have this issue with native apps, only Electron-based ones, so it seems likely to me that there is some performance issue with this sort of input to Electron.
