I've been experiencing the same bug for about the same amount of time. Slack and Keybase seem to cause the most problems for me. Both of those are built on Electron which has an open issue (https://github.com/atom/electron/issues/465) about this bug. My guess is that this less an Ubuntu bug and more an Electron one.
