Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a valgrind log following the instructions at https://wiki.ubuntu.com/Valgrind and attach the file to the bug report. This will greatly help us in tracking down your problem.

I read the wiki.
ibus-ui-gtk3 start automaticaly at boot, how to start ibus-ui-gtk3 only with valgrind?

Sorry for my english

[rws (robert-schlotterbeck+launchpad)]

Me too. Also running 13.10 x86_64 with ibus 1.5.3-6ubuntu2.1

I have two of these processes running (two users logged in with Unity desktop). After about 1 week, one process is 8MB while the other is 16GB.

% ps -eo comm,rss | grep ibus-ui-gtk3
ibus-ui-gtk3 7896
ibus-ui-gtk3 16786100

No Valgrind data here, either. This was the first and only (observed) occurrence.

I too am experiencing this problem (twice so far since upgrading to 13.10 and I don't think I had the problem before that).

The system becomes fairly unresponsive e.g. can't unminimise windows from the launch bar and it may not even be possible to minimise windows.

I can start System Monitor and it shows that ibus-ui-gtk3 has taken 8GB of memory (half what I have) and growing quickly. I have not let it get beyond that. I think that logging out clears the problem.

PS I don't think this problem should be allowed to expire because of its "incomplete" status. It seems a fairly serious problem to me.

If you want valgrind information, you are going to have to provide additional information about how this process gets started - if it is even possible to use valgrind in this case.

Same problem here. 1.3 GB of RAM used by ibus-ui-gtk3.

[Ryan Davis (ryan-mokeys)]

Same problem here. Computer went to sleep and work up with 4GB used by ibus-ui-gtk3. The only funny thing I did today was `kill -HUP gvfsd-metadata` because it was eating my disk trying to index network shares that I don't care about.

[Chris Brower (idrum4316)]

I'm also having the same problem. ibus-ui-gtk3 is using 3.6GB of memory.

Seeing 2.9GB on 14.04 LTS desktop 64 bit

[Launchpad Janitor (janitor)]

[Expired for ibus (Ubuntu) because there has been no activity for 60 days.]

[Stephanus Teggy (rystian)]

Saw 1.8GB mem usage on 14.04 desktop 64 bit - this might help http://askubuntu.com/a/490326

[Kiko Rodriguez (ibagazha)]

If you don't use any different keyboard layouts for ex. japanese /asian etc. you can try with that:

Happend to me too on Ubuntu 14.04 64bit. ibus-ui-gtk3 has taken 1,6GB of RAM

[Dan Kegel (dank)]

Bug 1276186 may be an acute form of this bug.
I saw both the high CPU usage and extreme RAM usage (about 1 megabyte/second leak).
It happened when I minimized Chrome, but continued long after I killed all the chrome processes.
ibus-ui-gtk3 got up to 2+ gigabytes of ram pretty quickly. I'll attach an apport log.

I guess I could figure out how to valgrind the app by disabling ibus in System Settings / Language Support,
then following https://code.google.com/p/ibus/wiki/IBusStartUpTroubleShooting,
or maybe by looking at the startup hook installed by im-config and modifying it.
But since I don't need an input method, I may just live with ibus disabled.

seems to have happened to me once in a 1-2 years of usage on 16.04.

ibus-daemon + ibus-ui-gtk3 > 5 GB RAM usage

[Dennis (moneysac)]

I can confirm that this bug ist still present in Ubuntu Ubuntu 16.04.2 LTS.
ibus-daemon and ibus-ui-gtk3 allocated together at least 2GB of ram. They also caused together approximately 40% CPU load.

I'm impacted with this issue in ubuntu 16.04 LTS. It sucked up 7.5 GB of my RAM and my system became extremely slow.

[Ilya Kopysov (justletmedie)]

I'm impacted with this issue in Ubuntu 17.04. It consumed 6.5GB of my RAM and I killed it after I noticed freezes. I believe it because I used "Suspend" instead of "Turn off" 3 days in a row(though my computer was working 3-5 hours per day. So its around 12-15 hours).
