Applications like VLC are no longer able to display video Looks like some kind of resource allocation problem, although system ram and cpu usage appears to be fine (ie: if something is leaking, it's not those resources) Did not happen before 4.8.0 Appears to happen after several hours (~6) of system uptime.

One of your plasma widgets has a memory leak. Try to find out which by removing one of them.
On Wed, 21 Mar 2012 02:34:42 AM you wrote: > One of your plasma widgets has a memory leak. Try to find out which by removing > one of them. fair enough... thanks for the quick reply. I would add that my widget set didn't change from pre 4.8.0 either - pretty minimal: - one folder view (desktop folder) - one note - three icons - analogue clock - system load viewer - hardware temperature - network activity (all out of the standard set of widgets) I've never done any work with desktop widgets. What do you think of these assumptions: (1) the icons and the note are probably not leaking. (2) that any leak is because of some activity (3) that the more activity, the more likely the leak (like the network or the temperature). Is there some method or tool I can use to monitor the resource usage of an individual widget? I'm happy to do trial-and-error but that could take a while. cheers, d

Sorry, not used to the tracker yet. Application: plasma-desktop KDE Platform Version: 4.8.00 Operating System: 3.2.0-20-generic Distribution: Kubuntu 12.04 I may have been affected with the same error. I was away from the laptop when it happened, though. It had crashed before with sympthoms similar to what happy described (wrong widget background). The only widgets I have installed that were not on in Kubuntu 12.04 by default were System Monitor and Icon Tabs.
Haven't worked all the way through the set of applets running individually but can't reproduce it yet. The System Load viewer (not yet tested) is looking likely - temperature and network activity don't appear to be the cause.

(In reply to comment #1) > One of your plasma widgets has a memory leak. Try to find out which by > removing one of them. In my case, if I removed all the widgets and left an empty plasma desktop, it wouldn't crash. Then I tried to add a standard panel back (with task manager, system tray, digital clock), it crashed after some time. Now I'm testing with an empty panel only.
Current status: The plasmoid that caused plasma-desktop crashed seemed to be system tray on a panel. I restarted a standard panel and removed system tray, it didn't crash so far. If I started an empty panel and add system tray into it, no any other plasmoids, it would crash. Later I'll try if I put the system tray on the desktop instead of panel. But I wonder if anyone would have the same symptom as mine.
I found a source of problem... It was knemo... i just removed it fully (yum remove knemo) and restarted system... now have no problem during 24 hours online =)
Thanks for the investigation. Now it would be interesting to find out which widget or application in the system tray causes the issue. For example, try removing mixer applet or update notifiers, or whatever else is hidden there.
(In reply to comment #24) > Thanks for the investigation. Now it would be interesting to find out which > widget or application in the system tray causes the issue. For example, try > removing mixer applet or update notifiers, or whatever else is hidden there. Here's a possible root cause: the nepomuk indexing. If the nepomuk file indexer was disabled, it wouldn't crash. I've been testing it for at least two hours and am still testing it. I also disabled printer applet, korganizer reminder and akonaditray, but nepomuk file indexer is the most possible root cause because it also explains why my desktop PC wouldn't crash like that in my laptop.

Hello everyone I found at least one possible way to reproduce this bug: 1. I use psi-im as messenger 2. On every new message, it flash icon in system tray 3. On KDE 4.9.3 it produce X11 memory leaks from plasma-desktop at rate around 50Kb/sec (I've measured from ksysguard) So I've bisected at found that offending commit is: commit ae04d14bd4977225787169adb88d88da7a19de74 Author: Luboš Luňák <l.lunak@suse.cz> Date: Wed Oct 5 12:25:28 2011 +0200 less Xlib code, force Qt to use X pixmap for QPixmap instead REVIEW: 102770 I've reviewed that commit and have made a patch, that works for me: diff --git a/plasma/generic/applets/systemtray/protocols/fdo/x11embedcontainer.cpp b/plasma/generic/applets/systemtray/protocols/fdo/x11embedcontainer.cpp index 1826512..eabea6a 100644 --- a/plasma/generic/applets/systemtray/protocols/fdo/x11embedcontainer.cpp +++ b/plasma/generic/applets/systemtray/protocols/fdo/x11embedcontainer.cpp @@ -236,7 +236,7 @@ QPixmap X11EmbedContainer::toX11Pixmap(const QPixmap& pix) return pix; Pixmap xpix = XCreatePixmap(pix.x11Info().display(), RootWindow(pix.x11Info().display(), pix.x11Info().screen()), pix.width(), pix.height(), QX11Info::appDepth()); - QPixmap wrk = QPixmap::fromX11Pixmap(xpix); + QPixmap wrk = QPixmap::fromX11Pixmap(xpix, QPixmap::ExplicitlyShared); QPainter paint(&wrk); paint.drawPixmap(0, 0, pix); paint.end(); Can someone else also review/confirm this?

Process X is slowly growing in memory usage (200 Mb and more) and makes memory leak during maximum 6 hours. When starting system without Skype - there no problem - uptime 32 hours, process X amounts 32-64 Mb memory. Is anybody can fix this problem? Because Skype community is silent as dead...
Looks like another duplicate of the tray code leaking X pixmaps. *** This bug has been marked as a duplicate of bug 314919 ***
