More likely it is something with unity8, but not impossible Mir is at fault. But without some kind of crash dump, and it being extremely hard to reproduce, this is hard to solve.
A crash dump was generated, and hopefully uploaded to our servers. You can see them by visiting System Settings, Privacy & Security, Diagnostics, Previous Error reports (opens webbrowser). Can you share any unity8 reports here?
