--- Comment #9 from Silas S. Brown <silas-kde at flatline.org.uk> ---
This must be a quirk of the Asus eeePC hardware and the way the font renderers
or X11 drivers use it.  I get a similar problem when working in large print in
all non-KDE applications including Terminal, WINE, ... on Ubuntu 11.10 (without
KDE) on an Asus eeePC 900.  About the only application that doesn't do it is
Wenlin running on WINE.  Wenlin does not use any text output API; it does its
own font rendering and sends bitmaps to the screen.  Everything else uses the
system to render text and there lies the bug (somewhere).

About 15% of letters are affected, apparently at random.  Once a particular
letter is affected (say, lower-case 'n'), that same letter will take the exact
same broken form next time it's displayed.  So the broken form must be being
stored in some kind of glyph cache.

As I was running the Compiz window manager, I wanted to try turning off OpenGL
and/or compositing, but when I ran "ccsm" to do so, ccsm segfaulted whenever I
tried to change any of the settings.  (Reducing my DPI setting before running
ccsm does not fix this.)  However, I can confirm that the problem does not go
away when I switch to the Openbox window manager (which is not compositing).

As this isn't a KDE problem, would it be possible to somehow "move" this bug
report into the correct forum?  (but where would that be?  I'm suspecting Xft
but I could be wrong)
