High memory usage of Xorg and kwin after Xorg security updates

Bug description:
Hello,
since the Xorg/nvidia security updates last week, I encounter a problem with
growing Xorg and kwin memory usage.
In one hour the memory consumption is at Xorg ~ 270 MiB and at kwin: 300 MB ,
so the system responds slowly and scrolling is very slow in in dolphin, kwrite,
firefox, etc.
After several hours the system is so slow, that only a restart helps, and
then the growing of memory starts again.
*** My Tests;
I tried several nvidia drivers, but without success (from:
https://launchpad.net/~xorg-
edgers/+archive/ubuntu/ppa/+index?field.series_filter=precise)
304.125-0ubuntu0.0.1~xedgers12.04.1
331.113-0ubuntu0.0.1~xedgers12.04.1
346.22-0ubuntu1~xedgers12.04.1
(With purging each nvidia driver and fresh installing it)
*** My configuration;
Two Kubuntu 12.04.5 PCs with a nvidia card;
nvidia driver 331.113-0ubuntu0.0.0.3 and 304.125-0ubuntu0.0.0.1
One pc with the Trusty Xstack (HWE) with Trusty kernel
(3.13.0-43.72~precise1) and the other one with the stock kernel
(3.2.0-74-generic #109) and stock xstack.
I use one pc in my office, so it disturbs my work because of the slowness and
restarts.
Thank you for your help!
Best regards, Bernhard
