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

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
