Just to follow up on my last post, apparently compiz on KDE 4.8 runs as long as you don’t use the KDE/QT Event Loop plugin, but do select the text plugin (CCSM, under image loading).
I don’t know the source of the instability, but if the KDE/QT plugin is selected, the following error is presented:
glibmm-ERROR **: unhandled exception (type std::exception) in signal handler: what: call to empty boost::function Trace/breakpoint trap (core dumped)
Also worth noting, I had trouble using the default window manager. But, if you place:
as the window manager (Compiz Settings Manager -> Window Decoration Plugin -> General Tab -> Command), it seems to work.
I’ll have to explore more, but it does seem to be working, for now.
