>Plasma will crash on me 2-3 times per day just doing regular things This is not normal. Do a RAM test to see if you have a hardware issue.

RAM or the GPU is faulty. Definitely not normal. I've been running plasma for over a year, there was like 1 crash during the 5->6 transition, it's otherwise been perfectly fine.

I have the same issue, only on KDE, never anywhere else. Does KDE use RAM differently than every other software?
- fooker 9mo ago
  Yes, KDE aggressively caches and indexes things by default whenever you have free RAM unless you disable this behavior in multiple places in multiple applications. For example, in Okular you can tune it to choose how much of a pdf you want to keep rendered in memory, if you have a tonne of memory, this makes it the smoothest pdf viewer I have ever used. It has become reasonable graceful in giving it back when you you need it nowadays.

    The Linux kernel does this too, yet it does not crash like KDE. At any given moment, most of your free RAM is used to cache stuff by the kernel, unless you've recently rebooted.
    - fooker 9mo ago
      No, what the Linux kernel does instead is randomly kill user processes :) It's kinda infamous for that, and had held up Linux adoption for a decade or so. But you sort of missed the point, I think. The comment chain was about speculating why KDE could possibly crash if there was faulty RAM while other software would be fine. And the kernel absolutely crashes when there's faulty ram.

        Right, yet it's KDE that is crashing with extreme regularity, and never the kernel.

It’s normal if you use the Nvidia proprietary driver. Every notification leaks one fd, so if you get a lot of notifications it’ll segfault once or twice per day. This was apparently fixed in version 590 of the driver which was released only recently: https://forums.developer.nvidia.com/t/fd-leak-with-explicit-sync-and-kde-plasma/317293/38 https://forums.developer.nvidia.com/t/fd-leak-with-explicit-...

  So that must be why I'm not affected. I have a gtx1080 which can't use that driver. Good to know.

It is normal for KDE. KDE is mockingly called KrashDE in Linux circles for a reason. We're only 4 days into 2026 and there's already dozens of crash-related bugs filled in the bug tracker: https://bugs.kde.org/buglist.cgi?bug_status=UNCONFIRMED&bug_status=CONFIRMED&bug_status=ASSIGNED&bug_status=REOPENED&field0-0-0=product&field0-0-1=component&field0-0-2=alias&field0-0-3=short_desc&field0-0-4=status_whiteboard&field0-0-5=content&limit=0&order=changeddate%20DESC%2Cbug_id%20DESC&query_format=advanced&type0-0-0=substring&type0-0-1=substring&type0-0-2=substring&type0-0-3=substring&type0-0-4=substring&type0-0-5=matches&value0-0-0=crash&value0-0-1=crash&value0-0-2=crash&value0-0-3=crash&value0-0-4=crash&value0-0-5=%22crash%22 https://bugs.kde.org/buglist.cgi?bug_status=UNCONFIRMED&bug_...

  You know what else has a dozen crash related bugs in the bug tracker per day? Literally any piece of complex software. See LLVM for example. LLVM is the backbone of most compiler work in the world right now. https://github.com/llvm/llvm-project/issues https://github.com/llvm/llvm-project/issues
