[Bug 1605180] Re: Compiz hogging CPU when screen off
This bug was fixed in the package unity - 7.4.0+16.04.20160906-0ubuntu1
---------------
unity (7.4.0+16.04.20160906-0ubuntu1) xenial; urgency=medium
[ Marco Trevisan (Treviño) ]
* SwitcherView: always disable animations when in lowgfx mode (LP:
#1602784)
[ Andrea Azzarone ]
* When locked discard damages from windows below lockscreen. (LP:
#1605180)
* DecoratedWindow: display unmaximize button if the window is
vertically or horizontally maximized (LP: #1608480)
* Make sure the switcher detail view is properly scaled. Also scale
the xy_offset to make sure the switcher and launcher do not overlap.
(LP: #1605256)
* Close session dialog on first ESC. (LP: #1521116)
* Filter out scrolling envents for FilterExpanderLabel. (LP: #1604632)
* Disable menu discovery animation if MenusDiscoveryDuration is 0.
(LP: #942962)
* Redraw fake decorations on window resize. (LP: #940470)
* Use compiz::Window::serverNext instead of compiz::Window::next in
IsWindowObscured as the latter can be outdated just after
scale/spread terminates. (LP: #1614116)
[ Marco Trevisan (Treviño) ]
* DecoratedWindow: avoid deferencing an invalid shadow texture ptr,
and split functions (LP: #1608464)
* DecoratedWindow: display unmaximize button if the window is
vertically or horizontally maximized (LP: #1608480)
* DecorationsForceQuitDialog: make CSS selectors work with gtk 3.20
* UserAuthenticatorPam: ensure pam_handle_ is null initialized and
don't proceed if not set (LP: #1611668)
* DecorationStyle: set css name for Gtk 3.20
* OverlayRenderer: properly decorate launcher/panel when the launcher
is at the bottom (LP: #1611694)
* OverlayRenderer: don't use rotated textures, just rotate them at
rendering time
* SpreadWidgets: add container for spread filter and new spread
decorations (LP: #1283314)
* WindowButton: properly partially unmaximize a window when
middle/left clicking in the restore button (LP: #1616136)

Title:
Compiz hogging CPU when screen off
Status in unity package in Ubuntu:
Fix Released
Status in unity source package in Xenial:
Fix Released
Bug description:
[Impact]
My CPU is constantly hogged @ around 15% by Compiz when the screen is off. Just waking the screen up is enough for the usage to go down again.
[Test case]
1. Lock unity and wait for the screensaver to start
2. log in to your machine using SSH
3. Check the compiz CPU usage using 'top' or similar
[Regression potential]
Lockscreen view could not be updated (damaged) correctly
