Committed on 18/12/2023 at 17:23. Pushed by akselmo into branch 'master'. Fix kickoff crashing plasmashell after screen turnoff If kickoff was opened rapidly after screen turned off, it would crash. This fixes it. M +1 -1 shell/autohidescreenedge.cpp https://invent.kde.org/plasma/plasma-workspace/-/commit/65cf607857e516d0335058ff49909052a154b1da |
SUMMARY When powersaving turns screen off, and user starts using the PC after a while (screen turning back on), opening Kickoff few times rapidly will crash plasmashell. Unsure if this is because of using fullscreen Kickoff, or if it happens with all of them. STEPS TO REPRODUCE 1. Let screen turn off either by waiting or running `kscreen-doctor -d off` in terminal 2. Wait couple more minutes to make sure screen is actually off 3. Move mouse to turn screen back on 4. Open kickoff menu rapidly multiple times OBSERVED RESULT Plasmashell crashes EXPECTED RESULT No crashes SOFTWARE/OS VERSIONS Operating System: Fedora Linux 39 KDE Plasma Version: 5.90.90 KDE Frameworks Version: 5.247.0 Qt Version: 6.6.0 Kernel Version: 6.6.6-200.fc39.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 15.5 GiB of RAM Graphics Processor: AMD Radeon RX 6600 ADDITIONAL INFORMATION Using kdesrc-build workspace Backtrace: #0 __pthread_kill_implementation (threadid=<optimized out>, signo=signo@entry=11, no_tid=no_tid@entry=0) at pthread_kill.c:44 44 return INTERNAL_SYSCALL_ERROR_P (ret) ?
