I have 4500MHD and I was not seeing your problem, but wanted to give your
packages a test run.

I also have experienced display redraw problem, but slightly different than
what Ken reported (as I use KDE):
- I use autologin
- when I have unlocked the screen
- some KDE notification was drawn (wifi connected)
- when notification should be removed, only part of the notification window went
away
- this was similar as bug I was before only experiencing with EXA [1], but I
am running UXA now (much better performance, no redraw problems, only problem
with X crash on resume [2]
I will test this a bit more, as I have seen this only on autologin+autolock,
just after unlock. I do not see regular redraw problems when moving windows,
minimizae/maximize, as I have seen before with EXA. Will report back when I
get at least a day of experience.

Luka
