Hello,
since the Xorg/nvidia security updates of the last weeks, I encounter a problem with growing Xorg and kwin memory usage in KDE.
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 (GT 430 and NVS300); KDE 4.8.5
nvidia driver 331.113-0ubuntu0.0.0.3 and 304.125-0ubuntu0.0.0.1
One pc with the Trusty Xstack (HWE, xserver 1.15.1) 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.
Furthermore I opened a ubuntu bug report, but at the moment there is no progress.
There are no error messages in Xorg or syslog.
You can easily reproduce this, when you start in KDE the system monitor krunner (Ctrl+Esc), then search for kwin.
Do not start other applications and watch the process memory growing.
Thank you for your help!
Best regards, Bernhard
