I  have this bug (also as bug 1508219 which is now marked as duplication
of this report) on three different machines, each of them were verified
via ssh, that indeed, compiz uses 100% CPU when screen is locked. All of
them is up-to-date 15.10, one notebook (intel), one desktop (also
integrated intel stuff onboard), and one another desktop but with
AMD/APU configuration.  I also see wild memory leaking like happenings
on one of the machines at least (others are not used with long enough
uptime to be able to notice, maybe?), eg, according to top, memory usage
of compiz starts from something like 4% but it's 14% after three days of
being locked, it was also 41% after a week or so once ... And yes, CPU
is always at 100% at the momemnt I lock the screen even without power
saving of monitor, etc. On all of those machines. Quite annoying,
because of fan noise, and especially on the notebook, it's not so great
for the battery to have long on battery usage, as you can imagine :(
