Description Matthew Woehlke 2018-01-05 16:45:28 UTC

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.
