Description of problem: After upgrade from F23 to F25 mate-screensaver' "blank screen" mode doesn't really make the screen blank. It just freezes the screen picture until mouse/kbd activity. Version-Release number of selected component (if applicable): mate-screensaver-1.16.0-1.fc25.x86_64 Steps to Reproduce: 1. Run mate desktop. 2. Select "blank screen" in screensaver settings. 3. Do nothing. Wait. Actual results: No visible screen changes after screensaver activation. Expected results: Black screen after screensaver activation.
Use simply another screensaver theme for the moment, see other report https://bugzilla.redhat.com/show_bug.cgi?id=1397900 *** This bug has been marked as a duplicate of bug 1397900 ***
