Bug ID: 429047 Summary: systemsettings and kmail get stuck scanning fonts and consuming 100% CPU when started under Wayland in Sway Product: systemsettings Version: 5.20.2 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: devuran...@gmx.net Target Milestone: --- SUMMARY KDE applications like systemsettings or kmail do not show any window when being started. They keep running in the background with 100% CPU utilisation. When running them under strace (`strace systemsettings`), the output are lines like the following, over and over again (i.e. I see the same files and folders being scanned again and again, ad infinitum): openat(AT_FDCWD, "/usr/share/fonts/noto/NotoSans-Regular.ttf", O_RDONLY) = 22 fcntl(22, F_SETFD, FD_CLOEXEC) = 0 fstat(22, {st_mode=S_IFREG|0644, st_size=509848, ...}) = 0 mmap(NULL, 509848, PROT_READ, MAP_PRIVATE, 22, 0) = 0x7ff7541fd000 close(22) I am running Sway (Wayland) for my window manager. STEPS TO REPRODUCE 1. Start Sway 2. Open a terminal 3. Run `strace systemsettings` OBSERVED RESULT The same font directories are scanned again and again and no window is shown. EXPECTED RESULT I see the system settings window. SOFTWARE/OS VERSIONS Linux: 5.8.14 KDE Plasma Version: 5.20.3 KDE Frameworks Version: 5.75.0 Qt Version: 5.15.1 ADDITIONAL INFORMATION `systemsettings5 --version` says it is version 5.20.2, but my package manager says version 5.20.3 is installed. -- You are receiving this mail because: You are watching all bug changes.
