One issue I have with Electron is that if I put my computer to sleep without restarting it and have all the applications up all the time, Electron apps gets very slow and sluggish and lags very much. Slack is a good example of this.

I have to restart my computer every now and then in order to keep using Slack and Atom, because otherwise it lags so much. I don't know, I think I prefer UWP apps instead.
