(入力メソッドオフ and 入力メソッドオン, actual original English text may vary) The crash can be reproduced sometimes. -- Backtrace: Application: KWin (kwin_wayland), signal: Segmentation fault warning: Can't open file /memfd:gdk-wayland (deleted) during file-backed mapping note processing warning: Can't open file /memfd:kwayland-shared (deleted) during file-backed mapping note processing warning: Can't open file /memfd:wayland-cursor (deleted) during file-backed mapping note processing warning: Can't open file /memfd:JSVMStack:QtQml (deleted) during file-backed mapping note processing warning: Can't open file /memfd:JSGCHeap:QtQml (deleted) during file-backed mapping note processing warning: Can't open file /memfd:unknown-usage:QtQml (deleted) during file-backed mapping note processing warning: Can't open file anon_inode:i915.gem during file-backed mapping note processing warning: Can't open file /memfd:smithay-client-toolkit (deleted) during file-backed mapping note processing warning: Can't open file /memfd:JITCode:QtQml (deleted) during file-backed mapping note processing [New LWP 1433778] [New LWP 1433842] [New LWP 1433840] [New LWP 1435764] [New LWP 1433827] [New LWP 1433828] [New LWP 1433826] [New LWP 1433811] [New LWP 1433825] [New LWP 1433841] [New LWP 1433829] [New LWP 1433843] [New LWP 1433844] [New LWP 1435763] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1".

/usr/src/debug/kwin-6.4.1-1.fc42.x86_64/src/main_wayland.cpp:635 Reported using DrKonqi
Created attachment 183450 [details] kcrash report from drkonqi The problem has appeared multiple times again for the last few days even after recent system updates. One time I noticed the IM indicators had weird < > (left and right arrows) below the icons before kwin crashed, could be related? Corresponding kcrash file attached.
update: bug still exists and is very much reproducible, even without the Input Method Selector addon. kwin crashes pretty much a few times a day (since I frequently switch IMEs, a few times every few minutes). The current situation is that the IME information and the text suggestions (idk the correct name… candidate list?) never pop up at the correct place. Instead, it either doesn't show up at all, or resides at the top left corner of my main screen. Fortunately I can kinda live without text suggestions for both languages. I think the worst thing is I can't downgrade kwin currently due to dep issues so I hope this gets fixed soon because every time it crashes, most other apps crash too (keepassxc, firefox, discord, neovide, you name it)
