While my xscreensaver was up asking for the password (my desktop was "locked"); I noticed a notification popup from steam indicating a friend had just started playing a game.

Expected results:

  • Those popups should not appear or if they do "paint" behind the screensaver.

Current results:

  • Notifications are painting on top of the screensaver showing notifications bypassing the "unlock" feature of xscreensaver.

You can reproduce this by locking your screen; and having someone else join a game that's on your friends list.

I consider this a security issue as steam has essentially bypassed a core component of desktop security.
