Version: unspecified (using KDE 4.5.2) OS: Linux 1. enable "Thumbnail Aside" effect 2. activate the effect for one of the windows 3. lock screen. The thumbnail does not hide. Similar issue: https://bugs.kde.org/show_bug.cgi?id=179924 Reproducible: Always
Confirmed and not surprising: the thumbnail is always rendered. The effect needs to know when the screen is locked. It has nothing to do with #179924
Git commit bee4a6b15454e99469bfa17900cf5c0bdbc4ad5e by Martin Gräßlin. Committed on 30/01/2013 at 13:07. Pushed by graesslin into branch 'master'. Notify effects when the screen gets locked EffectsHandlerImpl starts to monitor DBus for the screen being locked and provides this information to the Effect system by allowing them to ask whether the screen is currently locked and by emitting a signal when the screen gets locked/unlocked. This information is needed to ensure that no private data is shown on the screen. The following effects are adjusted: * taskbar thumbnails * thumbnail aside * mouse mark * screen shot FIXED-IN: 4.11 REVIEW: 108670 M +2 -0 kwin/CMakeLists.txt M +103 -0 kwin/effects.cpp M +29 -1 kwin/effects.h M +15 -1 kwin/effects/mousemark/mousemark.cpp M +1 -0 kwin/effects/mousemark/mousemark.h M +1 -1 kwin/effects/screenshot/screenshot.cpp M +9 -1 kwin/effects/taskbarthumbnail/taskbarthumbnail.cpp M +1 -0 kwin/effects/taskbarthumbnail/taskbarthumbnail.h M +2 -1 kwin/effects/thumbnailaside/thumbnailaside.cpp M +1 -1 kwin/effects/thumbnailaside/thumbnailaside.h M +18 -0 kwin/libkwineffects/kwineffects.h http://commits.kde.org/kde-workspace/bee4a6b15454e99469bfa17900cf5c0bdbc4ad5e
