I have similar problems, but sometimes it works fine as expected.
On my workstation, I can reproduce this problem as following,
1) press the Super key, open the launcher;
2) then press Ctrl + Alt + L, to lock the screen;
3) then the laucher and the main bar are still visible, though I can't operate on them.
