I shall, but just realised that on this machine (2GB quad-core)
it's possibly less useful here, as I'm using 1.4.10 (the kde 3.5.10
version) of Amarok. It's the only legacy KDE app I'm running,
with everything else being current Debian unstable. (I just found
the KDE4 version of amarok to be too painful, and I have enough
KDE4-induced pain at the moment.)
Without disk activity it becomes a more curious problem. What
video drivers are you using? I'm seeing some weirdness with some
apps - previously reported on this list, and attributed by others to
my video drivers - that very much appear to be application-specific.
What does KDE4's amarok and knode use as their datastore? I seem
to recall that amarok at least reverted to sqlite, even if you'd set
it up to use MySQL in the 3.x version. Not that I can see a way
that xorg could appear to own those types of processes.
Out of curiosity - and the lack of disk activity suggests this isn't
a problem - but what's your memory usage look like when this
happens? 'top , O , o' -- is handy during these moments.
