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:/
304.125-
331.113-
346.22-
(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-
One pc with the Trusty Xstack (HWE) with Trusty kernel (3.13.0-
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

Same behaviour regards increased memory usage of Xorg and kwin up to around 300 MB observed in kubuntu 14.10 (utopic).
Not causing any slowness at present though.
