Try using KDE more, and the video speed accelerates as the X Server caches
up more of images, widgets of KDE (QT). For some reason Xpmac, the LinuxPPC
X Server, doesn't particularly care for QT, it seems especially slow with
QT. Probably the easiest solution is to just use KDE more, as it will
accelerate alot over the first few times. (Kind of like breaking a new thing
in).

It also maybe a video problem with Xpmac, the default X Server for LinuxPPC
R4. It's kind of slow, especially on low-endish machines. A good replacement
would be Xpmac_mga, which you install according to these directions:

That's a QT bug, it causes the scrolling to be locked on, which really the
only way to fix that is to install a newer version of KDE or replace KDE
with GNOME. Also this is a KDE 1.0 spefic problem, you shouldn't have these
with a non-KDE app.

kterm is pretty buggy, the one you are talking about. It does seem to have
text refresh problem, so I exclusively use Eterm (enlightened terminal
application, really cool, does pseudo-transparency) or xterm.

They kind of are.... have to add to FOM someday...
