KDE just keeps getting better and better. Developers are working on a new screen-locking implementation which will cause screensavers to stop working. So, let's see, in 4.8 we won't be able to turn off compositing effects and now our screensavers will no longer work. What's next, no more mouse and keyboard support? (Shh, better not give them any more ideas.)
Developers are addressing a security "constraint" in KDE's screen-locking routine, which I guess some folks may welcome. But as a result, screensavers will be rendered inoperative. They hope to include a fallback in 4.8, but will remove that in 4.9. Martin Graesslin says they wish to replace the current engine with a "new solution" built using Qt Quick and they hope users will start to contribute new screensavers.
