Version: unknown (using 4.2.1 (KDE 4.2.1), Kubuntu packages) Compiler: cc OS: Linux (x86_64) release 2.6.28-11-generic I have dual monitors set up with twinview. I have 3 meta modes set up, one that uses both monitors at their maximum resolutions and another 2 that both use one or the other at their maximum resolutions. I switch between these using KRandRTray, or sometimes the display option inside System Settings. When I change between meta modes the desktop effects seem to disable. When inspecting System Settings it seems to indicate they are enabled, when they are clearly not. However when I disable them, apply, enable them and apply, they return.
Potentially related plasma panel issue. https://bugs.kde.org/show_bug.cgi?id=188207
