The title pretty much says it all: in your experience, which widget engine is most compatible (stable) when used in conjunction with the Compiz Widget Layer?
http://wiki.compiz.org/Plugins/Widget lists Screenlets, GDesklets, XDesklets, SuperKaramba & Moonlight Widgets as common engines but provides no data on which work best with Compiz.
Last time I used a widget layer I noticed that widgets didn't always stay on the layer (sorry can't remember which engine I was using, it was quite some time ago) - hence my question.
Right now I'm running Lucid.
I realise this may be somewhat subjective but I think your actual experiences matter.
