Seems to be a duplicate of bug #340515
To determine if the vino server causes the problem (you can't use top/htop to
view the cpu time in this case), you need to enter
{{
ps ax|grep vino-server serveral times
}}
{{
1)
3546 ? S 0:03 /usr/lib/vino/vino-server --sm-config-prefix
/vino-server-sNAKlu/ --sm-client-id
10745211812e4f72ae124308837940910700000063310022 --screen 0

6255 ? R 0:00 [vino-server]
6257 pts/0 S+ 0:00 grep vino
6258 ? R 0:00 /usr/lib/vino/vino-server
}}
As you might see the vino-server is started and killed so the process ID
increases. This permanent loop seems to be the reason for the CPU usage.
