Comment 3 for bug 1893781

I have similar behaviour. When I close lid, it suspends normally. When I open the lid, I see a glimpse (0.5s to 1.0s duration) of my desktop but login screen shows up. But the only difference is I get the login screen show up. I assume the glimpse of the desktop is also a bug but I couldn't find it through the search. This bug could be related to 1875025: https://bugs.launchpad.net/ubuntu/+source/xfce4-screensaver/+bug/1875025/comments/24 as I've turned off the 'Enable Lock Screen' on the screensaver preferences in the meantime until 1875025 is resolved.
