Comment 104 for bug 862430

Maybe a possible regression. I have noticed that the slow windows bug has reappeared. I have tested this on my intel graphics system. I think it is related to this fix:

Backport fixes for white window bugs seen with the NVIDIA driver.
    (LP: #729979) (LP: #1002602)

If I move a window with my mouse relative fast it stays on its position, only the mouse cursor is moving.
The problem occurs after using the Desktop for some time.
As it seems the following processes have relative high cpu usages while moving a window around:

bamf, dbus-deamon, compiz and X
