[xubuntu-users] ubuntuforums site scrolling jerky

[David Guerra]

If wireless mouse, unplug the receiver and plug it back in. I had the same
issue as you and that was the only fix. Even reboots didn't fix it.

As for the issue with Facebook. Seems a memory leak from their code. Why
someone would want Facebook open that much is beyond my understanding, but
there probably isn't a fix you can use. With all their Ajax calls going on,
it's going to cause issues.
