CentOS 7 + MATE : Folder contents not refreshed in file manager


I just migrated my workstation running CentOS 7 from KDE to MATE.

It looks like I'm having the same problem with the Caja file manager
than with Dolphin. Folder contents don't get refreshed automatically,
and I have to hit F5.

For example, when I download a file (say, a compressed archive) from the
Internet, I have to hit F5 to see the file in Caja. And when I extract
the archive, I have to hit F5 again.

Anybody knows where this nagging problem comes from?
