Comment 0 for bug 1769383

After an update from ubuntu 16.04 to 18.04 the dock is aviable on the lockscreen after user login.
I did not configure this knowingly. Also i can start every application which is available on the dock.
Settings, virtual box, visualstudio code and so on.

After the update to 18.04 i just configure the screen frequency to 144Hz and the night mode on. And attach the dock on bottom.

I later undid these customizations back to configuration before, but the dock is stil aviable on lockscreen.
