Bug ID: 388580
Summary: Memory leak in plasmashell
Product: plasmashell
Version: master
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: mwoehlke.fl...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
The plasmashell process exhibits systemic memory growth; it uses ~4 GiB
initially (with less than 10% of that resident), but grows significantly after
24-48 hours grows (most recently, to about 13 GiB; in this case, not much of
that was resident, but it was consuming about half my swap). This may be a
semi-recent development that has been occurring for a few months now (at least,
I don't recall seeing it in early 2017). It is very noticeable because
overnight my machine runs out of real memory and runs very slowly as stuff gets
swapped back in (often, after killing and restarting plasma).
kscreenlocker may also be affected. Some nights, one or the other of these has
been OOM-killed.
I've tried running under valgrind; the best, not-so-helpful backtrace suggests
there may be a GL context leak. To hazard a guess, this *may* be related to
using slideshow as wallpaper? Otherwise, I have minimal widgets; just a panel
with taskbar, system tray, clock and kdevelop session chooser. My screen locker
also uses slideshow.
