Expected: no cpu usage.

Actual: continuous cpu usage.
"bad aListVisibleBounds: 'r.GetBounds().IsEqualInterior(aListVisibleBounds)', file /home/karl/moz/dev/layout/base/nsDisplayList.cpp, line 956"
ad infinitum.
The assertion is dependent on theme.  I see it with Clearlooks, but not the default GTK theme.  CPU usage continues without the assertion.
