        <pre>There is a bug <a href="https://bugs.kde.org/show_bug.cgi?id=340031">https://bugs.kde.org/show_bug.cgi?id=340031</a> and videos showing
the problem:
<a href="http://ixion.pld-linux.org/~arekm/kde-4.14.2-konsole-bug.avi">http://ixion.pld-linux.org/~arekm/kde-4.14.2-konsole-bug.avi</a>

Initially I thought it is KDE konsole terminal bug but it doesn't seem to be
the case.

I was able to reproduce it on two machines.

My laptop:
- Intel(R) HD Graphics 4600
- kde 4.14.2, xorg 1.16.2, kernel 3.18.0rc4
- I use kdm to log in
- I use this script

$ more /etc/X11/kdm/Xsetup
#! /bin/sh
# Xsetup - run as root before the login dialog appears

/usr/bin/xrandr --dpi 141
/usr/bin/xrandr --output eDP1 --scale 0.6x0.6

to get 1920x1080 instead of native 3200x1800.

Note that dropping "/usr/bin/xrandr --dpi 141" from above makes the problem go
away.

So I log in using kdm, twm starts, then I run xterm and run KDE "konsole" from
it. In konsole vim /etc/passwd, then set cursorline and move cursors down and
up, just like on videos.


My PC:
- Intel(R) G41
- kde 4.14.2, xorg 1.16.1, kernel 3.17.2
- I use kdm to log in
- twm starts
- run xterm
- xrandr --dpi 80
- start KDE konsole
- under kde konsole: vim /etc/passwd; set cursorline; move up and down

I wasn't able to reproduce on friends laptop:
- Intel(R) HD Graphics 3000
- kde 4.14.2, xorg 1.16.2, kernel 3.17.2
- kde was running; xrandr --dpi XX (various XX values)
- konsole; vim ... ; set cursorline</pre>
