plasmashell, which is written in QML (JS-based), uses hundreds of megabytes, and sometimes leaks memory or bugs out (as far as I can tell, the leaking and instability/crashing is an interaction between QML/JS, the JS engine, and KDE's C++ classes exposed to JS through bindings).

After a week of uptime, plasmashell is consuming 350MB memory (taken just now from my process manager). Considering this is my work machine and I never reboot except kernel updates, I've never seen it leak memory or crash tho. This is Debian Testing with KDE 5.26.4 w/ Frameworks 5.100 w/ Qt 5.15. 350MB is not very optimal of course. I may dig the code to see the reasons, tho. XFCE4 had a similar memory leak ~2 years ago, which was triggered every time screen went into sleep and came back. So, bugs & shenanigans happens, but I'm not still sure that KDE is "hell of a bloat" considering the things it provides at the speed it provides.

  Checking coredumpctl, I've gotten two plasmashell segfaults in the past 4 months, and recall hangs and crashes happening more often in the past (especially under NVIDIA drivers). Additionally plasmashell has hung a few times and/or kwin terminated unexpectedly, though I think this is a Mesa bug (https://www.reddit.com/r/kde/comments/zbux1i/where_would_i_start_looking_to_debug_random_kwin/ https://www.reddit.com/r/kde/comments/zbux1i/where_would_i_s..., https://gitlab.freedesktop.org/mesa/mesa/-/issues/7674 https://gitlab.freedesktop.org/mesa/mesa/-/issues/7674) or amdgpu kernel bug (I've had multiple GPU driver hangs and unusable screens on sleep-wake, usually preceded by kwin dying in the same session).

    I also checked coredumpctl, and no KDE related crashes logged there, hence validating my experience. Funnily, both my desktop systems run on NVIDIA cards w/ NVIDIA drivers, and both have uptime numbers in multiple months at minimum. The personal desktop I used to use was regularly suspended to RAM and woke back, and my work system is on 7/24. Both are running KDE, and never misbehaved. They are not lightly used systems either. Also both installations use KDE extensively. Akonadi, Baloo, KIO, etc. are regularly used. At the end of the day, this is strange.
