Description Steve Gilberd 2009-07-29 19:55:40 UTC

Version:            (using KDE 4.2.4)
Compiler:          gcc x86_64-pc-linux-gnu-4.3.3 
OS:                Linux
Installed from:    Compiled From Sources

The twitter plasmoid (kdetwitter) leaks pixmaps and doesn't release the resources back to the system, resulting in ballooning memory usage by X.

This behavior can be seen by running 'plasmoidviewer twitter' and watching the number of pixmaps, and the pixmap memory used by this process in xrestop.

My standard settings are 5 tweets displayed, 2min refresh, show friends. On my system, this results in X eating about 1.2GB/hour of ram.

System Details:
Gentoo ~amd64, x86_64-pc-linux-gnu

USE flags for kde-base/plasma-workspace-4.2.4:
-debug -google-gadgets +handbook -kdeprefix +python -rss +composite +xinerama

Comment 1 Dario Andres 2009-07-29 20:58:46 UTC

Both bug 182900 / bug 201736 mentions leaks that were fixed on KDE4.3 code. Thanks

Comment 2 Aaron J. Seigo 2009-07-29 21:19:04 UTC

yes, these should be addressed in 4.3.

Comment 3 Steve Gilberd 2009-07-29 21:25:57 UTC

Awesome - thanks for the quick response, and glad it's been fixed already :-).

Comment 4 Steve Gilberd 2009-08-05 03:19:14 UTC

Now running KDE-4.3.0 release, compiled from source - the microblogging widget still exhibits the same behavior and has not been fixed.

Comment 5 Aaron J. Seigo 2009-08-05 06:29:08 UTC

how many people are you following on twitter, exactly?

Comment 6 Steve Gilberd 2009-08-05 06:38:36 UTC

Not many - I have around 10 following, and follow twice that.

Comment 7 Daniel 2009-08-15 17:43:01 UTC

Can confirm this here on 4.3.0 release, Gentoo ~amd64 & ~x86.

I am currently following eight people.

Comment 8 Christian Schubert 2009-08-20 18:28:20 UTC

can confirm this on debian sid

plasma-desktop used 130 MiB pixmaps (according to xrestop), after removing the twitter widget, plasma-desktop is down to 26 MB

130 MiB seems to be the cap for me, didn't see any higher value yet

Comment 9 Gerwin 2009-08-31 08:29:39 UTC

Count me in on 4.3 final @ Fedora...

Comment 10 Steve Gilberd 2009-09-11 00:59:19 UTC

Still happens on 4.3.1.

SVN commit 1070409 by mart:

never keep more than 30 avatars in user_map
hope it's enough to stop the X pixmap skyrocketing, not so sure

Comment 12 Daniel 2010-02-16 16:21:13 UTC

Still happens with KDE 4.4.0 (Gentoo ~amd64). X Memory usage goes up endlessly. This should be re-opened.

Comment 13 Dario Andres 2010-02-16 16:26:04 UTC

@Daniel: can you confirm that memory usage doesn't happen if you don't use the Microblogging widget at all ?
Regards

Comment 14 Daniel 2010-02-16 16:29:36 UTC

@Dario Andres: When I remove the Microblogging Plasmoid, memory usage drops immediately to a healthy value.

Comment 15 Daniel 2010-02-19 15:00:47 UTC

*bump* re-open?

Comment 16 Steve Gilberd 2010-02-19 22:04:29 UTC

I'm also running Gentoo ~amd64 with KDE-4.4.0, and I can't say I'm seeing this bug any more - memory usage by the microblogging plasmoid is just fine.

Could this perhaps be an entirely different bug with the same symptom?

only hold user pixmap data that is actually in use; prevents endless accumulation of random images over time
