It's probably worth asking upstream (Kwin) about that specific KDE
effect. I'm not familiar with that effect, but they are probably doing
something that the binary driver doesn't expect (and that used to work
only by accident). Just a thought.

After some testing now seems from my side at least that the raising of
unreleased memory usage by xorg is not related to the new xorg packages.
Seems to be a Chrome/Chromium bug as no other programs trigger this.

Bugs,
I must correct my comment#14, because with downgrading only the
xorg-server-core package, the problem persists.
You have to downgrade all xorg* relevant packages to a version before the
security updates of the last weeks, as Francis Brown mentioned.

High memory
All that had their version bumped by the security fix.
Have noticed something interesting. Increased Xorg memory usage here
seems to be somewhat related to using Chrome/Chromium (or based upon)
browser with hardware accelerations enabled in the advanced options.
Each time I launch an instance it
Unity compiz and Xorg processes are not growing, this seems like a KDE +
Nvidia + Xorg issue.
I tested firefox without hardware acceleration, but still growing kwin
and xorg processes.
You can easily reproduce this, when you start in KDE the system monitor krunner
(Ctrl+Esc), then search for
OK. In that case it is a subtly different problem from what I am seeing
then. If it persists I shall file a separate report.
