I definitely believe that it shouldn't be doing that and it was not
always the case. I am certainly willing to accept there is something
screwy with my upgrade path, but I did not do anything intentionally
to the theme or defendant components. (The only thing that comes to
mind that *might* be related is that I renice qpe to -5).
Even if the 20% CPU utilization went away, removing drop shadows so
the Software-16 engine can work seems worthwhile to me.
