empty power management page in system settings
flamegraph under zh_CN.UTF-8 locale |

Created attachment 178281 [details] flamegraph under zh_CN.UTF-8 locale I also captured a flamegraph using cargo-flamegraph[1], not sure if it helps. 1. https://github.com/flamegraph-rs/flamegraph I can reproduce the issue with those exact settings and running `LANGUAGE=zh_CN.UTF-8 systemsettings`. I can reproduce this issue also for zh_TW.UTF-8 locale. *** Bug 500933 has been marked as a duplicate of this bug. *** *** This bug has been marked as a duplicate of bug 499773 *** |
Created attachment 178280 [details] empty power management page in system settings SUMMARY The "Power Management" page in System Settings will hang, causing 100% single thread CPU usage, if the system is using LANG=zh_CN.UTF-8 locale, and font size in System Settings "Text & Fonts" page is set exactly as follows: General: 11pt Fixed width: 11pt Small: 9pt Toolbar: 11pt Menu: 11pt Window title: 11pt Font families and anti-aliasing settings don't seem to matter. STEPS TO REPRODUCE 1. Ensure zh_CN.UTF-8 locale is available (`locale -a` output contains `zh_CN.utf8`). On Arch Linux this means uncommenting zh_CN.UTF-8 in /etc/locale.gen and run `locale-gen`. 2. Change font size in System Settings as above 3. Close System Settings, launch it with `LANG=zh_CN.UTF-8 systemsettings` 4. Navigate to "Power Management", see it hang. OBSERVED RESULT Right side is empty (see screenshot), 100% CPU usage on a single core. EXPECTED RESULT Opens Power Management normally SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.3.0 KDE Frameworks Version: 6.10.0 Qt Version: 6.8.2 Kernel Version: 6.13.2-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 PRO 6850HS with Radeon Graphics Memory: 14.9 GiB of RAM Graphics Processor: AMD Radeon Graphics ADDITIONAL INFORMATION LANG=C.UTF-8 or LANG=en_US.UTF-8 are unaffected by this, but LANG=ja_JP.UTF-8 is affected.
