Tried that:
* Both the HDMI and VGA displays.
* VGA 1920x1080 everthing ok
* HDMI gets a desktop size which is larger than the screen. On all edges, 
about 2 cm of the desktop is carwed off (the left column of icons and the 
bottom panel in KDE). Additionally, th statics is there _but_ not as intense. 
xrandr and xdpyinfo both attests that both outputs are 1920x1080. It doesn't 
scroll as the classic "virtual large desktop" X thing.
The text looks stretched and the scroll list in Kterm shows a repeating wavy 
stretch pattern.

No improvement. Tried "shadowfb", "exa", "none", removing the line.
With randr (i.e. as above) I get less static. Maybe one horizontal line "blip" 
every 2 seconds. Without randr (i.e. with all of the desktop shown on the 
monitor), I get 4-7 lines jumping around more or less all the time. My 
imression is that I get more lines when I place some windows on the otherwise 
homogeneous blue background. I can send you a small video of the phenomenon if 
you want to.
