This was affecting me both when resuming from suspend, as well as when resuming from lock screen. I'm running a Dell XPS 13 9370 under Ubuntu 19.10, with two UHD displays connected via a dock. I wasn't necessarily seeing screen resizing so much as anything on a secondary screen was being closed.
After calling `gsettings set org.gnome.desktop.interface scaling-factor 1`, everything works normally for both resume and unlock operations, and all windows previously in use are still present.
