Bug#736580: kde-plasma-desktop: mouse cursor disappears when hovering in certain places

[solitone <solitone@mail.com>]

Hi, it seems there are no answers to this problem, isn't it? or perhaps 
am I missing something?

Anyway, I experience the exact same issues that Gerry reported, even 
though I use gnome:

$ dpkg -l gdm3
Desired=Unknown/Install/Remove/Purge/Hold
| 
Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name           Version      Architecture Description
+++-==============-============-============-=================================
ii  gdm3           3.4.1-8      amd64        Next generation GNOME 
Display Man

However, the problem is not there from the beginning, as soon as I log 
on and open a new gnome session It appears as soon as I open a root 
terminal from gnome menu (don't know whether this can possibly happen 
also with other actions).

Does somebody have any suggestion to solve it?

Cheers
