I would suspect the video driver. I have a Intel machine that is running
Slackware 14.0 and the display works fine with xterms but when graphics are
involved the display of the graphics has problems. I would check for a
graphics driver update.
I think this is the right information from the dmesg file:
input: Video Bus as
/devices/LNXSYSTM:00/device:00/PNP0A08:00/LNXVIDEO:00/input/input6
ACPI: Video Device [GFX0] (multi-head: yes rom: no post: no)
[drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0

Try xterm, or rxvt, or gnome-terminal
thanks Frank, and also Dan , for your suggestions, but
the problem is actually with xterm.
I also tried with rxvt: it's worse.
Withe kde x-terminal-emulator, no problem.
That would be Konsole, unless they've made a new one.
Here are the results of different tests
==> xterm -geometry 100x40+0+70 -ls good
==> xterm -geometry 120x40+0+70 -ls garbled screen
==> rxvt -geometry 80x40+0+70 -ls good
==> rxvt -geometry 100x40+0+70 -ls garbled screen
It looks like a bug, and I think I'll do a bug report, unless somebody
suggests something else.
I'd be suspicious of the video drivers… perhaps Xlib (xterm, rxvt?) is
triggering some bug in the video driver that Qt (Konsole) isn't.
qterminal is another Qt-based terminal emulator that might confirm
whether the widget set is having an effect.
