OK. I wasn't aware of what systems were in use for development.
As my bug report noted - the behaviour I'm describing occurs
whether I boot with my (few) 3rd party extensions, or with the Base
9.2.2 set. I can install a fresh system on an empty partition...
I'll let you know how that goes. Failing that, and given the
similarity with symtoms that others have reported, what's weird
about _your_ system?

Nope. I've taken that into account.
Abyss.pov renders at the speed I'd expect for 30 seconds, then
slows drastically - in the first 30 seconds it maybe manages 45
scanlines, in the next 15 minutes it manages about 15 scanlines.
The other file I've tried (referred to in the bugreport) can
complete (just) in 30 seconds with some rendering options (no
anti-aliasing, 320 x 240). If I turn anti-aliasing on (original,
0.3, 2, 0.1) then it also falis to complete, getting about 3/4 of
the way through the render at normal speed (30 seconds), then
slowing down.
Consistently: 28-30 seconds after the preview window is displayed,
my machine goes into near catalepsy - screen updates happen once
every 60 seconds thereafter.

I'll see what difference it makes. Thanks.

It's not the GUI that's annoying me, other than it's change in
behaviour indicates other things going awry.
Have Fun
