Hi!
I have ArchLinux with Qt 5.4, KDE Framework 5.7.0 and KDE Plasma 5.2.0 installed on laptop.
During launch plasmashell uses almost twice more, than in KDE 4.14. During use plasmashell utilize over 600MB - that is more than as for KDE.
Install was made by different way:
- by deleting KDE 4.14 and then installing Plasma 5 with KDE Framework from official repository ArchLinux
- by installing clear ArchLinux and after that installing Plasma 5 with KDE Framework
- by installing clear ArchLinux and after that compiling Plasma 5 with KDE Framework from git sources

No one of this methods does not improve situation with using RAM on Plasma 5. In this form it is not suitable for use, even with 5.2.1 version released. In 4.14 plasma uses ~60mb ram on cold start, and not more than 80mb during use whole day. At case of 5.2.1 - 600mb by half day. This is more than all system and browser.
Hope, that this very big issue will be fixed with nearest releases.

Here is my explanation screenshots:

most importantly, how did you close valgrind/plasmashell.
Almost all these traces are just in Qt and it seems unlikely that's the problem.

can all of you above try removing applets to see if we can pinpoint one
causing a problem.

Can you all above tell me what graphic card you're using + driver

The memory usage continuously rises while seeding with this app, after

Transmission-gtk is fine.

This continues through the latest beta to 5.3.

My suspicion is that non-native apps are the issue. I use sparkleshare
(a mono app), which I haven't managed to display in the system tray.
Whenever it's running, plasmashell memory usage starts going up totally
out of control.

Whereas "plasmashell" uses up to 2GB of Ram, Xorg.bin doubles the ram
usage. I have attached smaps and screenshots from ksysguard.

@ycollet
I believe that the problem that you have described is different from the one being discussed here. I think it will be good to create a separate bug report for the cpu load issue. Nevertheless, I have experienced the CPU rise issue in similar circumstances. It seems that whenever you put a frequently updated plasmoid either in the system tray or on the desktop, the cpu spikes.
In my case, whenever my plasma-nm or the notification icon are showing the spinner (the semi-circular stuff that spins around the a pertinent icon in the system tray to indicate that work is being done) for loading a connection or displaying the status of a copy job that takes a while to complete, my CPU usage goes wild, and I know that it is not caused by the connection or the copy job (i.e. the same copy on cli shows no issues.)

Okay so the point of this comment was to move the CPU issue into another
bug :). Sorry to divert from the discussion of this memory leak problem.

Hello.

I am having same problem on my desktop: plasmashell eats as much memory
as is can. I have even spotted 2g consumed in RES column of top.

After reading this bugreport I disabled tray icon for my Psi+ (it uses
animated icons) and memory consumption has gone. I can't say that having
no icon for IM is very convenient, but at least I don't need to restart
plasmashell every day.

So I think this info may be helpful:
• there was an animated tray icon from third-party Qt-4 application (Qt 4.8.6)
• it was definetely "animating" while my session was locked, usually it was blinkig for the whole night
• i am not using any screensavers, just lock screen.
• I had to remove the animated tray icon to eliminate memory consumption
• there is one more tray icon from some KDE application (it says I have updates for my system) which is not animated and seems not to affect plasmashell's memory consumption.

Thank you.

Same issue on Manjaro Plasma 5.3.1, KF5.11

I found one issue which causes memory increasement:
When I click to the panel to add widgets, plasmashell CPU usage became about 10% from zero and memory increases continuously (about 30 MB in a minute).

Even if there is no change on the panel the memory increasement does not
disapear.

Other programs may increase plasmashell as well as after a few hours
plasmashell memory takes about 600MB instead of the starting 200MB.

But for one issue, there is the add widgets function in the panel which
creates huge memory usage.

Memory usage of plasmashell climbs drastically (in like 30mins, not sure
yet if this related to background kio_ssh file copy), desktop becomes
choppy, when mem usage reaches 6.6GiB (sic!) it crashes.

Not sure if this is the same issue, but when the memory usage is high
the desktop starts flickering when I select applications from the

I think we can be pretty sure it happens with certain system tray icons.

qbittorrent spits out TootltipChanged signals once a second, the others
probably do the same. Which means if there is even a tiny leak updating
SNIs, it will fill up pretty quickly.

Though, I still can't reproduce locally, and valgrind showed everything
being fine.

There was a fix in Qt > 5.4.1 to some QtDBus memory allocation.

Can someone confirm they still have it with that version of Qt?

Can people start a list of what apps trigger this, maybe we can find a
useful pattern.

Finally, could someone with a leak capture the dbus traffic on their system whilst the memory is increasing.
ideally with bustle, or worst case dbus-monitor.  Note these may contain personal information from whatever else is running, so be careful before sending.

David, transmission-qt on Arch Linux with all latest plasma and
Qt-5.4.2, is still increasing RAM as before, as I enable
Prefs>Desktop>"Show Transmission icon in the notification area".
Disabling it stops it.

Have not tried bustle, however notice that it is in the AUR. Please post
how to use and grab what/where the information you need.

You can simply restart plasmashell (kquitapp5 plasmashell && sleep 5 &&
plasmashell & disown). logging off/logging back in also restarts Xorg
process in case it is eating up memory as well. You don't have to reboot
your machine.

I have almost the same situation except that htop and ksysguard shows
that plasmashell only uses  (~80MB-90MB) but my whole system is out of
free memory.

After plasmashell restart and type "echo 1 > /proc/sys/vm/drop_caches" everything back's to normal.
This happen on my laptop (Intel graphics) and older second PC-box (Radeon card).

After some debugging I ran plasmashell with GALLIUM_HUD="requested-VRAM,requested-GTT,VRAM-usage,GTT-usage" and noticed strange thing.
VRAM goes to max, then GTT goes to max. After VRAM and GTT is full then htop and ksysguard show that something start eating my free memory. I'm not sure if this is possible but it looks like if VRAM and GTT is full then mesa/driver/etc is trying to use system memory. The eaisiest way to reproduce this is hovering over taskbar and desktop items.

I know nothing about OpenGL but I can imagine that textures are not
removed and we have memory leak :)

Dmitry can you run plasmashell with GALLIUM_HUD (if you are using noveau
mesa driver) and see if you will have similar effects ? :)

It's always happening, having a pretty fresh kubuntu 15.10 install (with

anything to get this backtraced.

Interestingly, for me, extremely reproducable if I'm running Wine OpenGL

application, it seems to be pretty stable.

But why would plasmashell freak out because of wine OpenGL applications?

Fact is, as soon as I start an OpenGL application in Wine (as WoW),
plasmashell it leask 920k/s. As soon as I close it, it stops leaking.
Note that normal Wine applications don't start the leak, as in example
the Battle.net Launcher.

So that seems to be connected at least.

I guess this generalization is too wide: I don't play games at all, but

Can you try my suggestion please? close all applications including system tray ones after disabling swap. restart kwin_x11/plasma and ctrl+alt+f3 or f4 and then ctrl+alt+f1 back to your X session.
I would like to know if ctrl+alt+f* operations are triggering garbage collection in Xorg.

I usually don't have swap enabled. The memory usage goes down when I
close the apps and switch to a TTY to kill plasma and kwin_x11 (more
from closing apps than anything else) but the leaked memory seems to
remain.

Note though I only tried this when X was using about 300MB of memory (it
starts with about 100). I will try it when the memory usage goes up
again to the gigabyte range.

> I think infinality patches can cause issues

I've never had issues with them. I can try switching, but call me
skeptical.

Thank you. That is what I was trying to figure out.
If I understand correctly, closing an application and then switching to a TTY and back causes Xorg to release the xserver memory used for that application. If memory leaks remain afterwards, then this indicates issues with the xorg driver and the compositor (kwin_x11 in your case).

Few minutes is very short time for test with clock.

Faster test:
 - download plasmoid thermal monitor and set:
     - refresh speed - 0.1s
     - create 5 fields for temperature monitoring (physical id and 4 cores)
 - in this test is leak speed is 12MB / minute

Is any chance for use memory leak profiler please? For example compile plasma-workspace with library jemalloc and use jeprof.
Valgrind is too slow and not monitor during run. But jemalloc is ideal library for memory monitoring.

I tried leak with thermal monitor on second pc. Leak exists, but it is
slower (500kB / minute) . But for leak need set 6 virtual workspaces.

I have a handful of systray icons which are handled by the xembed-sni-proxy, and I wonder if that contributes.
Also, if I let plasmashell's stdout and stderr come to my terminal window, I see xcb errors every time i move my mouse pointer over the taskbar and hover from one window marker to the next.
I don't know if either of these facts are helpful.

I cannot confirm i use it regular since it created, not remember, not

Of the two patches listed here as resolving this (very important) problem, one is for plasma-breeze and the other is for qt5-qtdeclarative. It looks like the latter is only committed against QT 5.6.

Rex (or other Fedora-type person), how can we communicate to the relevant Fedora package maintainers that we need a backport of this for QT 5.5.1 ?
(It looks like KDE bug 357800 for breeze is already in a 5.5.x context, and not a problem in master.)
