I know this is not very helpful, but I noticed exactly the same thing
with my Asus UL30A this weekend (and KDE, too). I know it used to work
before, but I haven't used the second monitor for a long time, so it
may be broken for quite some time.
I have found only a partial solution, and that is to disable effects
before connecting a monitor. After the second screen is connected,
even the cursor movement becomes unbelievably choppy, but after a
while everything goes to normal for me. When I left the effects on,
the system stayed unusable.
