Plasmoid movement is not always smooth. Mind the "always".
Actually it works perfectly well about 50% of the time.
The other fifty percent however are rather painful :
the plasmoids won't move until the mouse is released or
no mouse movement happened during several seconds which
induce a strong feeling of irresponsiveness.

This bug really annoys me and I'd gladly help fixing it
if anyone can point me in the right direction (no KDE 4
programming background yet but more than two years working
on Qt 4 apps should do).
