Application: plasmashell (5.27.1) Qt Version: 5.15.8 Frameworks Version: 5.103.0 Operating System: Linux 6.1.12-060112-generic x86_64 Windowing System: X11 Distribution: KDE neon 5.27 DrKonqi: 5.27.1 [KCrashBackend] -- Information about the crash: Hi there! So ever since a few recent updates, plasmashell has been crashing a LOT on me randomly. It first pins 1-2 threads to 100% and then eventually dies. --------------------------------------------------------------------------------------------------------- System info: OS: KDE neon 5.27 x86_64 Host: Vivobook_ASUSLaptop M3401QA_M3401QA 1.0 Kernel: 6.1.12-060112-generic Uptime: 13 hours, 39 mins Packages: 2430 (dpkg), 7 (flatpak), 15 (snap) Shell: bash 5.1.16 Resolution: 2880x1800 DE: Plasma 5.27.1 WM: KWin Theme: [Plasma], Breeze [GTK2/3] Icons: [Plasma], breeze-dark [GTK2/3] Terminal: konsole CPU: AMD Ryzen 7 5800H with Radeon Graphics (16) @ 3.200GHz GPU: AMD ATI 03:00.0 Cezanne Memory: 13368MiB / 15398MiB --------------------------------------------------------------------------------------------------------- This has gotten so frequent that I have been running plasmashell on a konsole window (which i keep open so i can alt+tab to, cuz when the plasmashell crashes, the taskbar disappears too) I think it has something to do with the task bar? the taskbar is the most visible one when plasmashell freezes/crashes, because it auto hides itself (never to unhide itself till i alt tab to konsole n restart plasmashell). it also leaves a "ghost" of what i had over that portion of the screen before it crashed. it crashed again while i was typing this report, it is pretty common for some reason. The high memory usage in the system info is due to me working on something kinda heavy, but it also seems like plasma is taking 16.8% of the memory (according to htop at least) The memory usage seems to keep on growing with plasma, extreemely slowly, but it seems to? i mean im pretty certain it wasnt 16.8% when i booted up or was working on it for the first few hours I tried a bunch of stuff to reproduce it, but it seems pretty intermittent. I did get it to work a few times but i feel like it was some sort of fluke. I get messages like this right before it hangs/crashes. (more "Unable to assign [undefined] to QQuickItem*" lines below but i didnt include because they look similar) ```

Darn, sorry this is happening. Any chance you can install debug symbols for Plasma and get a new backtrace?
Created attachment 156911 [details] Plasmashell backtrace this is the backtrace
Created attachment 156912 [details] Plasmashell error when run from console This is an error I got from running plasmashell via console (`plasmashell -n -d`). This was not the same run as the one with the backtrace (since i kinda forgot to run `thread apply all backtrace` (woops sorry), but this error has also happened a few times)
Hi there No problem! You guys are doing amazing work. I have attached the backtrace as well as a crash image now, please let me know if i can provide anything else that might help with the diagnosis Thanks
Thanks! Unfortunately the new backtrace you've provided doesn't look the same as the original one, and it's not clear there's a crash at all. "QBuffer::writeData: memory allocation error" doesn't look good either . :/
Oh yeah, I see. Could it be that multiple things are causing it to crash? should I maybe record multiple backtraces and add them all?
Hi, yeah I think I'm fairly certain that its something to do with the taskbar, the taskbar is the most visible issue when plasmashell dies. now i dont know if its a cause or a symptom, but more often then not its the taskbar that freezes first (with everything else working just fine) before everything comes crashing down
Hi. I have similar symptoms: plasma crashes 5-10 times per day. KDE Neon user 5.27.2 Qt Version: 5.15.8 Kernel: 5.19 AMD graphics as well, X11 session. I feel that it started with 5.26 or 5.25. Maybe this string from logs could be meaningful: Mar 12 11:05:34 adept-XPS-13-9360 kwin_x11[1331661]: kwin_core: XCB error: 152 (BadDamage), sequence: 58753, resource id: 5517981, major code: 143 (DAMAGE), minor code: 3 (Subtract) For me, most often, it reproduces when I have multiple notifications simultaneously. But even without a notification, it can crash. Please LMK if I can help somehow. Thanks
I'm also getting multiple random daily crashes. Although the mouse still works, all windows are frozen. Getting to a terminal with Alt-Ctrl-F2, I can see processes still running. I have tried a few things from there. If I try to kill and restart plasmashell, I get errors: qt.qpa.xcb: could not connect to display qt.qpa.plugin: Count not load the Qt platform plugin "xcb" in "" even through it was found. This application failed to start because no Qt platform plugin could be initiatlized. In order to recover I thus have to do a hard reboot. In the journalctl logs, besides the type of entries already mentioned (kwin_x11: kwin_core: XCB error: 152 (BadDamage)), I also see the following type of entry about 10 to 15 seconds before the whole window manager freezes over: plasmashell[2151]: Could not find the Plasmoid for Plasma::FrameSvgItem(0x56017bc10820) QQmlContext(0x560177a81aa0) QUrl("file:///usr/share/plasma/plasmoids/org.kde.plasma.notifications/contents/ui/global/Globals.qml") plasmashell[2151]: file:///usr/share/plasma/plasmoids/org.kde.plasma.notifications/contents/ui/NotificationItem.qml:220:21: QML SelectableLabel: Binding loop detected for property "implicitHeight" I really don't know whether this bears any relationship to the problem.

@Jean-Sébastien Caux, how do you try to start plasmashell? DISPLAY=:0.0 plasmashell ?
Today I restarted plasmashell killall plasmashell && kstart5 plasmashell and saw some new errors when it failed: QWidget::paintEngine: Should no longer be called QPainter::begin: Paint device returned engine == 0, type: 1 QPainter::setRenderHint: Painter must be active to set rendering hints QPainter::setCompositionMode: Painter not active QPainter::setCompositionMode: Painter not active qt.gui.imageio.jpeg: Corrupt JPEG data: premature end of data segment
(In reply to Yuriy Vidineev from comment #11) > @Jean-Sébastien Caux, how do you try to start plasmashell? > DISPLAY=:0.0 plasmashell ? I was trying `killall plasmashell && plasmashell &` and also `killall kwin_x11 && kwin_x11 --replace` and also `kquitapp plasmashell` and the `kstart5 plasmashell` but none of those worked.
