Hmm, I don't see any KDE code in the backtrace. Looks like it's very deep in the guts of the QML runtime. *** Bug 500444 has been marked as a duplicate of this bug. *** *** Bug 501027 has been marked as a duplicate of this bug. *** Bug 498246 has a similar trace, and seems to be triggered frequently by the cat walk widget. Removing that widget seemed to remove the issue at first, but it still happens at a much lower frequency, see bug 501027. *** Bug 502853 has been marked as a duplicate of this bug. *** Created attachment 180318 [details]
plasmashell crash screencast
On my dupe issue, I briefly managed to get this to happen in a reproducible way:
1. Make the preview modal really big for one grouped task icon by opening a lot of windows.
2. Tricking the preview modal for an adjacent task icon to be too big by hovering over the first icon and quickly moving to an adjacent one. (I can reproduce this reliably).
3. Sometimes (?) this will make hovering over the second icon (the one with the tricked preview size) crash plasmashell 3-4 seconds after you hover it. When this starts happening you can reliably crash plasmashell indefinitely by repeating this. Eventually, perhaps after opening and closing some windows, this stops happening again. I suppose I can't prove that (2) is definitely related but it does seem very suspicious in this context. In the original report, activating *any* icon causes the crash. In this followup, it's specifically the icon with the wrong preview modal size.
I've attached a screencast of this happening.
My dupe issue has an interesting traceback that actually touches a Plasma lib in one place, and that might help someone track this down:

Backtrace with Plasma 6.3.5 with Qt 6.9.0
I can confirm that this is still an issue on Plasma 6.3.5 with Qt 6.9.0.
I had the crash occur multiple times on different devices, but am unsure how to reliably reproduce it.
It feels like it happens in random moments when you least expect it.
Hopefully the attached crash report is more useful.

Similar crash report for this issue
I am seeing something similar, although slightly different (thus, not sure if this would be better as a separate bug report). In my case, it seems not only to occur when hovering over/selecting an entry in the icons-only task manager but rather other widgets can trigger it too. For example, I have the media player widget on both of my panels (I have two monitors, both have a panel on them) and clicking one of them recently triggered a crash. That being said, it tends to have a higher chance of happening with the icons-only task manager widget.
I'll attach a copy of the dump from systemd ("plasmashell-crash.log"), my system details are as follows:
Operating System: CachyOS Linux

Memory: 64 GiB of RAM (60.4 GiB usable)
Graphics Processor 1: NVIDIA GeForce RTX 5070 (this same system was previously using a Radeon 6700 XT, which this crash was still occurring with)

(In reply to Russ from comment #17) > Created attachment 183556 [details] > Similar crash report for this issue That looks like a different crash to me, based on the backtrace. I'd report it separately, though note that it would be easier to debug your issue if you had the debug symbols. I think you can get them on Cachy like this: coredumpctl gdb 48634 Respond y to the prompt asking you if you want to auto-download debuginfo. Then, after it downloads all the debug symbols and returns you to the "(gdb)" prompt, type bt then hit return. You can copy paste the response to this prompt. Because the crash is in the main thread, this is probably all you need. *** Bug 507704 has been marked as a duplicate of this bug. *** Created attachment 184166 [details] Backtrace with Plasma 6.4.4 and Qt 6.9.1 This just happened to me on Plasma 6.4.4 and got a very similar backtrace. I reproduced the crash by doing the following: 0. Have multiple apps already open at the same time 1. Open a media player with MPRIS support (in my case, Audacious) and play some music 2. Hover over an icon in the task manager 3. Wait for the tooltip to appear 4. Shake the mouse cursor sideways (or up and down if it's on a vertical panel) over the other icons and the Pager widget to the left 5. Watch as one of the tooltips get stuck, plasmashell becoming completely unresponsive and eventually crashes I have the task manager and pager widgets set up on a top panel exactly like in the video in comment #6, with window previews enabled in the task manager settings. However, I couldn't get plasmashell to crash or even lag with the same steps above if I turn off window previews. I also noticed that when I hover over an app icon other than the one playing media, the window preview tooltip would randomly perform a shrinking effect on its bottom side the moment it appears. I suspect that the crash is related to that animation, which I think it feels out-of-place anyway. Operating System: EndeavourOS KDE Plasma Version: 6.4.4 KDE Frameworks Version: 6.17.0 Qt Version: 6.9.1 Graphics Platform: Wayland This is deep in Qt and there are no new traces with Qt 6.9.2 Lets consider this fixed, if someone can reproduce with > Qt 6.9.2 please reopen a new bug report Or re-open this one *if it's the exact same backtrace.* Created attachment 185146 [details] Backtrace with Plasma 6.4.5 and Qt 6.9.2 I just reproduced this with Plasma 6.4.5 and Qt 6.9.2 according to the steps outlined in comment #20. The backtrace is identical to attachment 184166 [details] and in comment #14. I have also sent this same exact backtrace to the developers using Dr. Konqi. Indeed, Sentry confirms we're still getting new reports from people using Qt 6.9.2; see https://crash-reports.kde.org/organizations/kde/issues/77440/ Created attachment 185726 [details] Backtrace with Plasma 6.4.5 with Qt 6.10.0 (also in QTBUG-141105) I am still having this crash with: KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.18.0 Qt Version: 6.10.0 (In reply to Nate, comment #1) > Hmm, I don't see any KDE code in the backtrace. Looks like it's very deep in the guts of the QML runtime. Since I was unable to find a relevant QTBUG, I reported this issue to Qt now: https://bugreports.qt.io/browse/QTBUG-141105 I would be happy about further information or feedback for it! (In reply to Adam, comment #6) I am only able to reproduce the *UI issue* where the Task Manager window previews staying too wide after hovering from a window group with a lot of windows onto one with just two. However, I am unable to reliably reproduce the crash. It still seems to happen "at random" for me, but unfortunately still regularly. (In reply to Russ, comment #17) I agree with Adam. That looks like a different crash to me. But due to the missing debuginfo, not much can be read from it. :( Based on the mention of the Media Player widget, you might have had an issue with bug 509192, or both (like me). According to Sentry, the frequency has dropped off a ton recently, even if we're still seeing a few cases. Lowering priority. *** Bug 511106 has been marked as a duplicate of this bug. *** > Since I was unable to find a relevant QTBUG, I reported this issue to Qt now:

Today, that bug has been fixed.
Applied patch, still can reproduce. Slightly different backtrace though.
(Sorry for manual paste, DrKonqui and splitdebug aren't friends so far...)

(In reply to Nate Graham from comment #27) > *** Bug 511106 has been marked as a duplicate of this bug. *** Important thing to reproduce using instructions from this report: it's not enough for the preview popup to have a horizontal scrollbar, one of the previews must be offscreen. Fixed in Qt v6.10.1 and v6.8.6. https://bugreports.qt.io/browse/QTBUG-141105 Qt 6.10.1 is to be released 18.11.2025. Qt 6.8.6 is to be released 08.12.2025. See release schedules: https://wiki.qt.io/Qt_6.10_Release, https://wiki.qt.io/Qt_6.8_Release It would be great if anyone who has the Qt dev branch set up could triage this and confirm it fixing this issue. https://codereview.qt-project.org/c/qt/qtdeclarative/+/684694 (In reply to Martin Bednar from comment #29) > Applied patch, still can reproduce. Slightly different backtrace though. > (Sorry for manual paste, DrKonqui and splitdebug aren't friends so far...) Thanks for checking! I had skipped this long comment. Your backtrace looks very different. It would be neat if you could explore frame 5 a little and report what you find. Perhaps it's worthy of a followup in QTBUG-141105? (In reply to Martin Bednar from comment #30) > Important thing to reproduce using instructions from this report: it's not enough for the preview popup to have a horizontal scrollbar, one of the previews must be offscreen. Interestingly, I don't remember this being the case for most of my crashes. I don't use that many windows of one program. It appeared to be more random for me. But of course it's good that it helps reproduction! I notice the same visual bug you recorded in attachment 186142 [details], where the container stays wide, even though the program I hovered to only displays two window previews. However, I can't reproduce a crash on Plasma 6.4.5, Frameworks 6.19.0, and Qt 6.10.0 using this method on my system, even while playing video in Firefox... Perhaps you have a slightly different setup, e.g. I use Icons-Only Task Manager. (In reply to mydarkstar from comment #32) > Your backtrace looks very different.

I use Icons-and-Text task manager, plasma 6.5.0, frameworks 6.18.0. Updating frameworks to 6.19 now. I'll let it update overnight (Gentoo) and report in the morning. Created attachment 186282 [details]
backtrace post qt fix
Still crashes with frameworks 6.19.

It's never been 100% for me, but in this case it was under similar conditions to what Martin reported. This was with Qt 6.10.0 (rebuilt with patch) instead of Martin's 6.9.3.

I'm trying again, this time including both the QTBUG-141105 fix and also this one: https://codereview.qt-project.org/c/qt/qtdeclarative/+/688387 The latter was reported recently on the Qt bug as part of another way to trigger the same crash.

The patch in https://codereview.qt-project.org/c/qt/qtdeclarative/+/688387 doesn't apply to 6.9.3. And when I just copy the code manually, I get a compile error: > ‘PoolItem’ was not declared in this scope I could try upgrading to 6.10, but that won't be today ( probably not even tomorrow).

That's great news, thanks for confirming! *** Bug 512019 has been marked as a duplicate of this bug. *** *** Bug 512443 has been marked as a duplicate of this bug. *** |
Created attachment 172610 [details] kcrash info Every now and then, with no obvious cause, clicking on an icon in the Icons-Only Task Manager will crash plasmashell. When this happens it instantly restarts (my Plasma session is systemd), and if I click on an icon again I will immediately get another crash. I can easily crash plasmashell over and over many times this way. Eventually (after a minute or two?) the problem goes away, and the reason this happens is equally unclear. Switching windows via any other method does not cause a crash - *including* hovering over the task manager so that the preview widget appears and clicking one of the previews. I do have a multi-monitor setup, though that isn't related in any obvious way - it doesn't happen consistently when I switch monitors, and there's no visual glitch or any other indication this is related. I mention it only because it is unfortunately related to the Plasma crashes I see more often than not.
