Just noticed the screenlock freeze again, worked fine most of yesterday (mostly only had firefox open), then later installed GSConnect extension (was essential for getting an errand done) and had sublimetext open (around 15 workspaces open). See https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1976163 for associated info.
