After the macOS is woken up after a sleep with an external monitor attached, the text on retina looked blurred.  I could not get a reproducer in time, but I think it was because while I put it to sleep, the scene got re-rendered on the external monitor going from scale 2 to scale 1, but when woken up, the scene was correctly re-rendered for retina but the canvas was not resized, requiring it to be scaled.
