The workaround for this I've used with NetBSD 3.x is to disable all
compiler optimizations when building Firefox.  This makes Firefox
slower, but the glitches go away.  (I had understood the glitches were
due to compiler bugs in the GCC 3.x series.  I've been meaning to
upgrade to a 4.0 RC but haven't done so yet, so I can't comment on if
the newer GCC release fixes any of these troubles.)
