Comment 11 for bug 1769383

I am experiencing this issue too since the upgrade to 18.10. Sometimes in addition to the launcher I can even see an open program! Cannot use the program interface though before going to the unlock screen by pressing super + l and unlocking the system.

I have gnome-tweaks installed, used it only to activate the Yaru theme which was not working after the upgrade (bug 1798984). So I guess that doesn't qualify as play with it.
