Bug#841642: mate-screensaver: The screensaver blank screen no longer works

[Frederic MASSOT]

Package: mate-screensaver
Version: 1.16.0-1
Severity: normal

Dear Maintainer,

Since the update of MATE from 1.14 to 1.16, the screensaver "blank screen" does not appear.

When using "ctrl+alt+l" or after 5 minutes of inactivity the desktop is visible, if I move the mouse the unlock screen with the password request appears.

Mate-screensaver is in the process list. I have only one screen.

There are not many things in the logs:
$ journalctl --no-pager -b | grep -i mate-screensaver
matt-screensaver-dialog [10377]: gkr-pam: unlocked login keyring


Regards.
