Upgrade to cinnamon-desktop 4.6.2 with fix for gnome-rr scale leads to Cinnamon screen flickering (it is almost unusable) when external monitor is attached.
Steps to reproduce:
Attach external monitor to laptop
Login into Cinnamon
After login screen starts flickering. It is interesting that this issue doesn't happen when I login into Cinnamon first and then attach external monitor.
