I have what looks like the same issue. When I lock my screen with "Super+L" the first time it goes into a flickering screen and the second time it locks the session. Then I login again, one of my shell extensions does not work anymore (PutWindows), and to make it work again I have to uninstall and install it again. I also have the issue that the Ubuntu dock does not auto-hide anymore unless I restart the session. I am not sure whether these problems are all connected. I use Xorg on Ubuntu 18.10. All these problems arose after updating from Ubuntu 18.04.
