It's a desktop machine, no hibernation, has been powered on for 2
years. No multi-display set-up or anything fancy, just a plain
computer with a single monitor. Basically what I'm doing is
alternately logging in remotely and locally to the same machine using
the same account. When logged in remotely (using NX server), my
screen/desktop size is smaller than it is locally. It happens every
single time, happens in KDE 4.3 and happened in 4.2 and 4.1 as well.

I don't know C++ and am not familiar with KDE source code at all, so I
may be looking in the wrong place, but in
kdebase-workspace-4.3.0/plasma/containments/panel/panel.cpp it looks
like it is using the minimumSize/maximumSize values from the config
file when it initializes the panel. So, I tried an experiment:

I resized the panel to be slightly smaller than maximized, the values
in ~/.kde4/share/config/plasma-desktop-appletsrc changed to this:

[Containments][3][Configuration]
maximumSize=1590,38
minimumSize=1590,38


I then clicked "maximize panel" and it changed to this:

[Containments][3][Configuration]
maximumSize=1600,38
minimumSize=1600,38

So I suspect what is happening is that when I log in with a 1280 width
screen, the minimumSize/maximumSize in this file is changed to
1280,38. Then, when I login with 1600 width it reads the geometry from
this file, making my panel 1280 pixels wide and leaving a gap of 320
pixels. At least that's my theory. :) Maybe there needs to be an
"Always Maximize" option (if my suppositions are correct).

Thanks
Paul
