This happens GTK apps such as
evince. Occasionally if I hold a scrollbar down too long without scrolling really fast it goes into a slow mode and becomes useless. How can I disable the slow-scrolling mode?
(because posts are always better with images)
I find this quite frustrating because I have a decent dpi mouse and often I'm slowly scrolling while reading and then want to quickly jump to another place in the file but find I can't and have to re-click.
