Well, yes, but we aim to support really slow systems.

You can reproduce it on an Iyonix. If you go to 256 colours with error
diffused bitmaps, scale the page to 300% or so and fill a 1680x1050 screen
with a NetSurf window showing just that image, then you get the pointer
flicker as reported. (Assuming animations are enabled.)

The issue isn't processor speed but a NetSurf bug. We shouldn't be
redrawing the JPEG over and over but we are because behind it is an
animated throbber GIF, meant to show the image is loading before it loads.

The animation is still there when the page is fully loaded, and it still
requests that area to be redrawn.

We need to avoid redraw requests from obscured content.
