Resume from Sleep/Hibernation

[Alex Gabriel]

I recall having that problem as well, but that was with KDE 3.5, and
it's only happened with the new versions mentioned.  I've used OpenGL
screensavers for a while, and never had a problem.

I did come across this, however, just after I posted the message, so
this may be a known bug.  https://bugs.kde.org/show_bug.cgi?id=284045
