This is
CentOS 7 3.10.0-957.21.3.el7.x86_64
xdvik version 22.86 (Xaw toolkit)
Libraries: kpathsea version 6.1.1, freetype version 2.8.0
It is rather unfortunate that scrolling a .dvi file generated by
latex will hang at some point.
It is certain to happen. When it happens, i can do two things:
1. Wait, then after many seconds, it will move to a few pages down the road
since i have hit a few Enter strokes, which is not what I want.
OR
2. Click on the mouse, and the screen is refreshed immediately. The page
will go down a few pages down too.
I have used xdvi in many Linux (CentOS 6) and never have
such observation. On one older machine
with identical CentOS 7 setup, it is strange since fast scrolling is observed too.
So question: What goes wrong? How can I start to pinpoint the bottleneck?
Graphics card + Xorg (bad drivers?), slow hard disk (seems unlikely
since I have CentOS 6 on the same machine but no such
delay) I have not got a clue what can
cause this to happen.
In my experience
xdvi scrolls really fast even for a large document -- a main reason
I used it a lot. I do not know
why that combinations of OS and xdvi mentioned at the top is not
behaving properly.

graphic card seems okay..
