[v3] screen locks up when sleeping, and waking on external display at times.

[wayneforrest]

Description

When sleeping on one display (laptop screen), and waking up on an external display, a data race condition occurs.
This does not always happen, and have to repeat this several times. Each time the UI got stuck with a beach ball. Inspecting the process, showed several go routines backed up. Eventually the go race found the cause.

go build -race -buildvcs=false -gcflags=all="-l" -o bin/my-app-name
  # my-app-name
