Backtrace and description look good: I'm quite confident that we can create a test case for it. Possibly related to https://bugs.kde.org/show_bug.cgi?id=397577 I can't reproduce this crash on neon dev unstable. Operating System: KDE neon Developer Edition KDE Plasma Version: 5.15.80 KDE Frameworks Version: 5.57.0 Qt Version: 5.12.0 Neither can I. If the crash happens again, please reopen this bug report. |
STEPS TO REPRODUCE 1. open a CSD window (gnome mpv player, for example) 2. try to drag the window using a touch screen 3. dragging does not work but the window enters in "drag mode" 4. while the window is still in "drag mode", close it using the touch screen 5. apparently the window is closed, but it reappears after some milliseconds in "drag mode" 6. press enter key OBSERVED RESULT wayland session crashes and the system goes to login screen EXPECTED RESULT no crash SOFTWARE VERSIONS KDE neon Developer Edition KDE Plasma: 5.14.80 Qt: 5.11.2 KDE Frameworks: 5.52.0 kernel: 4.18.8-041808-generic Thread 9 (Thread 2526.2562): #0 0x00007fd25f8a09f3 in futex_wait_cancelable (private=<optimized out>, expected=0, futex_word=0x7fd25d2c8fb8 <QTWTF::pageheap_memory+57592>) at ../sysdeps/unix/sysv/linux/futex-internal.h:88 #1 __pthread_cond_wait_common (abstime=0x0, mutex=0x7fd25d2c8f68 <QTWTF::pageheap_memory+57512>, cond=0x7fd25d2c8f90 <QTWTF::pageheap_memory+57552>) at pthread_cond_wait.c:502 #2 __pthread_cond_wait (cond=cond@entry=0x7fd25d2c8f90 <QTWTF::pageheap_memory+57552>, mutex=mutex@entry=0x7fd25d2c8f68 <QTWTF::pageheap_memory+57512>) at pthread_cond_wait.c:655 #3 0x00007fd25cfd3954 in QTWTF::TCMalloc_PageHeap::scavengerThread (this=0x7fd25d2baec0 <QTWTF::pageheap_memory>) at ../3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:2359 #4 0x00007fd25cfd3999 in QTWTF::TCMalloc_PageHeap::runScavengerThread (context=<optimized out>) at ../3rdparty/javascriptcore/JavaScriptCore/wtf/FastMalloc.cpp:1464 #5 0x00007fd25f89a6db in start_thread (arg=0x7fd21dfb8700) at pthread_create.c:463 #6 0x00007fd25d94a88f in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95 Thread 8 (Thread 2526.2560): #0 0x00007fd25f8a09f3 in futex_wait_cancelable (private=<optimized out>, expected=0, futex_word=0x55dc5bd88f00) at ../sysdeps/unix/sysv/linux/futex-internal.h:88 #1 __pthread_cond_wait_common (abstime=0x0, mutex=0x55dc5bd88eb0, cond=0x55dc5bd88ed8) at pthread_cond_wait.c:502 #2 __pthread_cond_wait (cond=cond@entry=0x55dc5bd88ed8, mutex=mutex@entry=0x55dc5bd88eb0) at pthread_cond_wait.c:655 #3 0x00007fd25e27b94b in QWaitConditionPrivate::wait (time=18446744073709551615, this=0x55dc5bd88eb0) at thread/qwaitcondition_unix.cpp:143 #4 QWaitCondition::wait (this=this@entry=0x55dc5bd88cf0, mutex=mutex@entry=0x55dc5bd88ce8, time=time@entry=18446744073709551615) at thread/qwaitcondition_unix.cpp:215 #5 0x00007fd21f7c822b in FileInfoThread::run (this=0x55dc5bd88cd8) at fileinfothread.cpp:227 #6 0x00007fd25e27aadb in QThreadPrivate::start (arg=0x55dc5bd88cd8) at thread/qthread_unix.cpp:367 #7 0x00007fd25f89a6db in start_thread (arg=0x7fd21efba700) at pthread_create.c:463 #8 0x00007fd25d94a88f in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95 Thread 7 (Thread 2526.2559): #0 syscall () at ../sysdeps/unix/sysv/linux/x86_64/syscall.S:38 #1 0x00007fd25e26e594 in QtLinuxFutex::_q_futex (val3=0, addr2=0x0, val2=0, val=<optimized out>, op=0, addr=<optimized out>) at thread/qfutex_p.h:92 #2 QtLinuxFutex::futexWait<QBasicAtomicInteger<unsigned int> > (expectedValue=<optimized out>, futex=...) at thread/qfutex_p.h:107 #3 futexSemaphoreTryAcquire_loop<false> (timeout=-1, nn=8589934593, curValue=<optimized out>, u=...) at thread/qsemaphore.cpp:221 #4 futexSemaphoreTryAcquire<false> (timeout=-1, n=n@entry=1, u=...) at thread/qsemaphore.cpp:264 #5 QSemaphore::acquire (this=this@entry=0x55dc5be4ead8, n=n@entry=1) at thread/qsemaphore.cpp:328 #6 0x00007fd2470b499b in QtVirtualKeyboard::HunspellWorker::run (this=0x55dc5be4eac0) at hunspellworker.cpp:293 #7 0x00007fd25e27aadb in QThreadPrivate::start (arg=0x55dc5be4eac0) at thread/qthread_unix.cpp:367 #8 0x00007fd25f89a6db in start_thread (arg=0x7fd21f7bb700) at pthread_create.c:463 #9 0x00007fd25d94a88f in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:95 Thread 6 (Thread 2526.2558): #0 0x00007fd25d93dbf9 in __GI___poll (fds=0x7fd220004660, nfds=1, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:29 #1 0x00007fd2548ca439 in ??
