As someone who has been hit by every single one of these bugs[1][2][3] but somehow didn't get the VS Code problem I'm not at all convinced that is somehow inherent in using Electron.
I don't think I ever had a "IDE causing high CPU load in" problem in Delphi 2, 3, or 5. I did in Delphi 4, and I have in PowerBuilder, Sybase PowerJ (although there were much worse problems with that!), VB6, Eclipse 2, and I'm sure there are some I've missed.
That was a bug in Chrome (http://crbug.com/361587), it's not inherent to the technology. VS Code ended up implementing the logic in JS to work around it.

Bugs suck, but they happen.
