"I gave up on KDE4 some months ago as I couldn't get any sense out of it and whatever I tried couldn't get a fix.Always NVIDIA related problems and so slow you wouldn't believe.Strange because before that I ran KDE,Gnome and now LXDE all extremely rapid."
i find faster kde4 compared to gnome but e17 makes me eat dust(the cpu dust?
what you describe is the old kde4 desktop effects attacking again, kde again screwing up things, in kde3 i had the same problem, i had the stupid idea of enable transparency and shadows
try compiz in kde4, you will see a absurd difference, or even try it without any effect, doesn't hurt and still looks very well
"I'm glad I asked the question now and sorry if I wasted peoples time."
