I'm not able to reproduce with 1.18.3-0ubuntu1.1 on my 16.04 LTS laptop with external screen (higher resolution than built-in) and Intel graphics. Robert, any ideas?

I'm running it on Linux Mint - let me know if this bug is more appropriate for their issue tracker. I made a 1 minute video demonstrating the issue, which might be easier to understand than text.

I expected my computer to remain locked even though I had plugged in a new display. 4) The new monitor was not covered by LightDM, allowing me to interact with it. Additionally, parts of my laptop monitor became uncovered. Notes: My laptop display is a 3200x1800 QHD (HiDPI) display when it's standalone but I downscale it to 1600x900 when it has an attached monitor, due to Ubuntu's scaling issues when connecting HiDPI and regular monitors. It's possible that LightDM doesn't think to resize, or resizes incorrectly, when the laptop screen automatically downscales as the new display is attached. I use Nvidia's proprietary graphics drivers (nvidia-375) on a GeForce 840M.
