can you run "top"or "htop" on a console (e.g.:
<ctrl>+<alt>+<f1>)?

More info:
The background doesn't flicker at all. What is flickering are the panel and
the default icons on the desktop, many times a second.
If I succeed in bringing up the TDE menu (which, if I click enough times,
eventually does appear when I succeed in timing a click at a moment when the
desktop is accepting input), then the flickering stops for as long as the menu
is visible.
More info:
After a few minutes of I trying to use this (basically unsable :-( ) TDE, it
suddenly popped up a dialog that said that the screen was locked and requested
that I enter my password. When I did that, I was returned to the session, but
the flickering had stopped.
So that suggests the question: what causes the screen to lock and the popup
requesting unlocking to appear? Somehow that seems to be related to the
flickering problem.

The doubled-up instances of kicker and twin jump out at me as a possible conflict.
