           Summary: Kwin eats up all the system memory
           Product: kwin
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kwin kde org
        ReportedBy: ubuntu martin-graesslin com


Version:            (using KDE KDE 3.97.0)
Installed from:    Ubuntu Packages

I noticed that kwin sometimes starts to eat up all my memory. More than 80% are shown \
in top and I have 2 GB RAM installed. It makes my system unusable as it starts to use \
the swap with continuing I/O. I have to kill the X-Server. This only happens when I \
enable compositing. Actually I am running a KDE3 desktop just with kwin of KDE4.

I have the following effects enabled:
boxswitch
desktopgrid
dialogparent
diminactive
fade
login
logout
maketransparent
minimizeanimation
presentwindows
shadow

I have an NVIDIA Graphics Card (driver 100.14.19) and I use the following settings:
- OpenGL mode: Texture from Bitmap
- Texture filter: Bilinear
- Direct rendering enabled
- Improved window management
- shadows

I have no logs of what is happening when kwin starts to eat up all the memory. At the \
moment I have enabled the effects, but memory consumption is OK, although it is \
increasing. I'll try to get some more information.

here the part from top:
PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
11373 martin    15   0  492m 256m 244m S    1 12.9   0:11.18 kwin

RES and SHR are increasing all the time. In the output from kwin the following is \
repeating all the time - don't know if it has something to do with it: \
kwin(11373)/kdeui (KNotification) KNotification::slotReceivedIdError: Error while \
contacting notify deamon "The name org.kde.knotify was not provided by any .service \
files" kwin(11373)/kdeui (KNotification) KNotification::~KNotification: 0

If there is any way to gather more information, please tell me.
