This happened once before and it went away by itself, I think...or, I accidentally pushed some key that corrected it. Also, if it helps I have Sticky Keys on but I always have them on so I don't know why pages would flicker now.
I have seen this problem and it is either a poorly spec'd PC causing problems, settings such as virtual memory allocation, hardware issue or something as simple as below;
What kind of flickering is it and what kind of pages does it happen with?
I find that the pages that exhibit this behavior the most are ones with plugins like Java or Flash. This is because they are not drawn by the browser, but by the plugin, so there is a bit of a disconnect between the plugin updating its part of the page and browser drawing the rest of the page during a scroll. It is not as bad with a faster system since it can handle the updating much quicker than a slower system, but even so, with the advanced and dynamic web-pages of today, pages put a much heavier load on the CPU (they "scale" with hardware advances), thus causing lag on anything but bleeding edge systems for some sites.
