HiDPI: segfault, and scaling goes to 200%, if I turn my monitor on and off
I don't use HiDPI scaling (it's set to 100%) on my single monitor. Whenever I turn my monitor on and off with the computer on and connected, it goes to 200% scaling. This is entirely reliable.
If gnome-control-center is open, it segfaults and only changes scaling occasionally.
On Pop!_OS 19.04 with GNOME Shell 3.32.1 on the Radeon RX 580.
