I sometimes see exactly this
and also some flashing and partial loading with animated gifs.
I reckon at least some of it is due to b3tards, and is related to slow load times.
I notice it more in Safari, but I only use that on the iPhone, which tends to load b3ta slower than my PC. But I have noticed it in Firefox on the PC too, particularly when page loads times are slow.
