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.
Say, bottom panel hasn't something special: std menu, lancelot,
tasks, tray
and clock. Can overheating be such selectable? - I mean only KDE4
panels-
related problem takes place (say, my sone plays few games without any
problems, as well as, say, OOo/Qt/KDE and so on emerging ). And I
didn't
overclocked something. But have added few additional silent coolers
inside a
case :-)
Can overheating be so selective? I can't say for sure, but I can't see
it having so much work to do when displaying the wallpaper as if those
panels fade or slide. I presume they can be auto-hidden one way or the
other when not in use, and that effects would be enabled by default if
you have GPU acceleration available.
Speckles are somewhat characteristic, and most any videogamer will
recognise them - once you've had a graphics card or a Playstation
(type) console die on you, they are very recognisable.
The emerging won't have any effect on speckles, only GPU-related
activity. It depends on the particular games that your son plays
whether I'd say they're relevant. I'm no expert on Linux graphics (I
don't use it on the desktop myself), but I'd guess TuxRacer probably
does use the GPU whereas Frozen Bubble does not.
If you're able to turn the GPU's acceleration features off in X11 (or
the kernel?) and just treat it as a framebuffer device, then please
prove me wrong!
