Status changed to 'Confirmed' because the bug affects multiple users.

[Cristiano Gavião (cvgaviao)]

with my environment 16.04 in Dell 15R 5537-A20, this started to happen just after install the kernel 4.4.0-59-generic.

I just can't use the scale anymore and also I can't click any launcher icon with multiple instances nor can't use hot corners. If I do then compiz crash and restart.

It happens when I'm using the "spread all windows" functions in unity. Anything else seems to be ok.

Happens approx. 7/10 times when I click on a starter entry with multiple windows open.

I get the same errors as above.
