There is a shot of my screen (1.4MB, look at bottom and right panels):

crazy things happen :-) There is very long software chain from
kernel video
driver (intel in my case for on-board G965) to KDE4 itself (~amd64).
As a
result, I'm not sure where to dig in.
Looks like an overheating GPU to me.
Do you have accelerated graphics on for those panels?
I'll bet if you turn it off the problem will disappear.
The graphics card failed here on my Mac a year or two ago, and rather
than pay £200 for an Apple-branded replacement, I found a regular PC
graphics card on which a hacked firmware could be flashed. I have to
under-clock it a little, and if I'm not careful I get a very similar
effect to that in your pictures, but all over the screen.
If you're able to boot to Windows it might be worth playing an FPS -
if it crashes with graphical glitches then you may be able to get the
card (or m/board?) replaced under warranty.
Stroller.
