I just tested it on X11 and the inconsistent, weird reordering behavior is there but it doesn’t crash plasmashell, so it’s very well possible that it’s two different bugs. Kinda looks like Bug 488713, but that's about KWin, not Plasma. You don't need to upload the whole coredump, just a backtrace of the crashing thread, See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl I think there are totally different bugs. My backtrace is different (I posted it as attachment but maybe you prefer if it was posted inline?). Also, I noticed it only happens when I’m using a second screen, otherwise the reordering is perfectly smooth and behaving 100% as expected and without crashes it seems. So to summarize: - Working perfectly well with one screen - Weird reordering behavior with two screens on both X11 and Wayland - Crashes with two screen on Wayland Do you have windows group setting enabled? Right click icons only task manager -> configure -> behavior -> what does the group setting say? Oh I am stupid, I misread your message, disregard the comment. At least part of my problem will be fixed by https://bugreports.qt.io/browse/QTBUG-127821 Hum, doesn’t seem to change anything with Qt 6.8.1… Operating System: Arch Linux KDE Plasma Version: 6.2.4 KDE Frameworks Version: 6.8.0 Qt Version: 6.8.1 Kernel Version: 6.12.1-arch1-1 (64-bit) Graphics Platform: Wayland I'm not able to reproduce this on current git master with Qt 6.8.2. Can you reproduce it in Plasma 6.3.5 or later, with Qt 6.8.2 or later? 🐛🧹 ⚠️ This bug has been in NEEDSINFO status with no change for at least 15 days.

Created attachment 173930 [details] `coredumpctl info` of the latest plasmashell crash SUMMARY I have an icon-only task manager set to group by program name. If I have more than one window of a program open at a time and that I try to reorder them, first it works very badly (the window isn’t dragged at the correct place, or isn’t moved at all), and secondly it tends to crash plasmashell under obscure conditions but guaranteed to happen after trying a few reorders (< 10) or when closing the window list afterwards. Since I tend to like to have my two or three Firefox windows in the same order and that Plasma doesn’t remember them, I try to reorder them everyday before starting to use my computer and very frequently hit this bug. STEPS TO REPRODUCE 1. Set up a panel with an icon-only task manager 2. Open several windows of the same application 3. Click on the application icon in the task manager, and try to reorder the windows until it crashes OBSERVED RESULT Reordering of windows behaves weirdly, doesn’t work every time and often crash Plasma. EXPECTED RESULT Reordering of windows behaves correctly, consistently and doesn’t crash Plasma. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.6.0 Qt Version: 6.7.2 Graphics Platform: Wayland ADDITIONAL INFORMATION I don’t remember when it started but it started somewhere around the beginning of Plasma 6 or when I switched to Wayland. I have coredumps but they’re too large to upload here (~20M).
