Software :: Scrolling In Opera - Displaying The Chopped Image

since a few updates of Opera, I'm experiencing very choppy scrolling, which is hugely annoying. It looks as if the page were chopped up and only pieces of it were scrolling, with parts of the former content still displayed. Now this happens generally during normal usage, with nothing but the browser running. CPU usage is thus minimal. The effect can be circumvented for a few seconds if I force the browser to scroll a large part of the screen at once (using the cursor keys), which has the effect of displaying the chopped immage as a still for a second, after which scrolling is perfectly fine.

This looks as though it was an issue of the processor speed being deregulated; alas, /proc/cpuinfo states both cores to be at their minimum speed in either circumstances. I'm not switching to Firefox, Opera is the only non-free piece of software I've come to love.
