I was discussing this with someone yesterday, and I suspect it might be
an interaction between Webkit and the graphics system. Are you using
Intel graphics hardware?

Have you noticed any other behaviour like this, anywhere? (Especially in
the help browser or in browsers using native WebkitGtk, like Epiphany or
Midori).

While the slideshow can work around this, it's unlikely a bug in the
slideshow: all it does is change the opacity of elements, which Webkit
then draws.
