Public bug reported:

Similar to bug
https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1145770 and
https://bugs.launchpad.net/bugs/1138517 after I upgraded from Ubuntu 15
to 16 I noticed that Java applications (notably Eclipse) have become
very sluggish, slow to respond (as the Java process constantly consumes
70-100% of a CPU core), and often don't draw their window contents
properly (i.e. a button which is toggled between enabled/disabled
doesn't get redrawn to depict the change, dialog contents on e.g. the
Run Configuration dialog don't get drawn fully until I click on some
other widget in the dialog like a tab name or button).

I've had this problem on both my desktop and a laptop which were
upgraded from Ubuntu 15 to 16.  If I run metacity or mutter instead of
compiz then Java applications work fine like they used to.  If I disable
the Ubuntu Unity plugin in compiz (using ccsm) like another bug report
or post suggested then the problem does *not* go away.  So, I believe
there was some aspect of compiz that changed between Ubuntu 15 and 16 in
which an old bug was reintroduced or a new one (similar to a past bug)
was introduced.

I'm using Ubuntu 16.04 LTS and compiz 1:0.9.12.2+16.04.20160415-0ubuntu1
