Cannot click anything after x-pos>approx 1200

[ketralnis2]

I can't mouse over or click on anything that appears in an X position greater than about 1200. I can't pin it down to an exact number but it's somewhere around 1288 pixels. Mousing over resource tiles or buildings does not activate the right-hand overlay and doesn't show the outline that indicates what is being moused over, and clicking has no effect. It occurs both in normal mode and in map overview mode (or whatever it's called when you hit "m"). I've recorded a 20-second video showing the behaviour: https://youtu.be/EemWoFg3dQ4

The Y direction appears to be unaffected, or if it is then my monitor isn't tall enough to trigger it.

I have a widescreen display that's 2560x1080. This is Factorio 0.16.4 on Mac OS X El Capitan 10.11.6 (15G18013)
