--- Comment #123 from Troy Volin  ---
I know it's not exactly appropriate to discuss distro-specifics here, but I
know Rex Dieter is subscribed to this bug.
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.)

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.

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 find that the leak persists even when the screensaver kicks in (overnight),
so I wake to "kquitapp5 plasmashell && sleep 10s && plasmashell &>/dev/null &
disown" every day.
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.

Confirming that at least main memory leak is gone in plasma 5.5.2. Creating and
closing lots of windows (which triggered leak previously) doesn't seem to leak
anymore, as Xorg recovers memory after that windows were closed.

I never had swap enabled, and didn't use infinality either. For some reason I
haven't had the issue the last few days though, it looks like it fixed itself
for me. I have no idea what changed, maybe this is after I updated to Plasma

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).

I am having the same problem as André Vitor de Lima Matos. Here's what I know:

* Only killing the X server reclaims the memory (killing plasmashell/kwin_x11
doesn't release it); it leaks about 5GB per day
* Plasma/kwin 5.5.2 (has been occurring for a while though)
* EGL/OpenGL 2.0 are my compositing options, but it happens with xrender too
* Using Intel driver 2.99.917-r2, Xorg 1.17.4, Kernel 4.3.3
* No real widgets besides the default
* I run thunderbird from time to time (but leaks even when I don't run it),
firefox (5 or so tabs, no inordinate memory usage), pidgin (a few
conversations), konversation (about 35 tabs or so), and konsole (pretty much
vim, htop, and basic system administration tasks).
* plasmashell is using about 200M of memory, kwin_x11 is using about 40M of
memory
* xrestop shows nothing out of the ordinary
* Suspending does not worsen it (I don't hibernate)
* I run infinality
* I have only one tray icon not from KDE: pidgin, and it blinking doesn't seem
to worsen the problem after a cursory look
* Closing/opening windows doesn't seem to cause it (though it changes memory
usage slightly, it doesn't resolve the general leak)
* Rolling over the task manager (looking at thumbnails) doesn't cause it

I'm at a loss as to what more I can do, though, to elucidate the bug. It seems
to happen under ill-defined circumstances.

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 think infinality patches can cause issues

[plasmashell] [Bug 344879] memory leak in plasmashell - huge ram usage

--- Comment #102 from Hussam Al-Tayeb  ---
Anyone on NVIDIA proprietary driver and getting memory leaks in Xorg process,
can you try the following?
1) swapoff -a
2) quit all applications and anything minimized to your system tray but keep a
terminal open and restart kwin (kwin_x11 or something --replace & disown).
3) close your terminal application.
4) Then ctrl+alt+F3 or F4 then ctrl+alt+f1 back to your session.
5) swapon -a
6) Check if Xorg process is now using less memory (in other terms, if some
garbage collection happened).

I think the leak only happens when I play CS GO (OpenGL app) and plasmashell is
running. I now stop the plasmashell process while playing, and Xorg seems to
have a normal memory usage.

I guess this generalization is too wide: I don't play games at all, but the
leak takes place.

I think so too. Especially if wine was leaking in libx11, we'd see a different
pattern (other DEs would very likely leak too!).

I didn't experience this on native OpenGL applications (yet) though, but I'l do
some checks on that as well the next few days.

I have got - not scientific :) - feeling the leak is correlated with workspace
background: using solid color helps.

Interestingly, for me, extremely reproducable if I'm running Wine OpenGL
applications. There I've like 1mb/s mem leak. Running no 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.

Experiencing this as well for quite some time now. Went up to 2gb within 4
hours, 4gb within 8 hours. Pretty linear.

It's always happening, having a pretty fresh kubuntu 15.10 install (with
updates). I can reproduce it by being afk, so let me know if I can do anything
to get this backtraced.

I have the same issue, Arch Linux and Plasma 5.5. Xorg is currently using 1,2
GB of memory. Plasmashell 196M. It happened yesterday as well.
I'm not using infinality. I don't use suspend or hibernate.

xrestop of valgrind session

Ran Xorg with debug symbols (in Xorg server and Intel driver). Finished session
with Xorg (and valgrind) taking around 830M RES mem, 1120M VIRT mem.
Looks like creating windows increase memory usage. Closing windows free some
resources, but not everything.

In this one, memory usage looks more scattered than without valgrind or debug

xrestop

xrestop output, with Xorg at 655M res memory usage. Not too helpful, I think,
as look like a lot of memory is "missing", suggesting a memory leak inside X.

But exactly now, my Xorg is at 1G ram, and increasing, plasmashell 151M (ok). I
have not suspended this session, rebooted computer by the morning (kernel 4.3.1
update).
