Description Monica 2023-12-02 21:03:26 UTC
While running under Wayland, the Icon-Only Task Manager appears to hang, as observed by the clock not progressing. Task Manager is still usable by clicking on icons of programs that are currently open, but the state (e.g., currently in foreground, background, minimized, whether it's opened or not) does not change. Rebooting the system temporarily fixes the issue and occurs in seemingly random situations and does not appear to be load related.

1. Load Plasma 5 in Wayland
2. Wait

Time freezes and program states are stuck as of when the task manager froze.

The task manager runs reliably without freezing

Linux/KDE Plasma: 5.27.9
(available in About System)
KDE Plasma Version: 5.27.9
KDE Frameworks Version: 5.111.0
Qt Version: 5.15.11

The issue appears to be unrelated to GPUs, as I have tried to troubleshoot this with a GTX 1080, RX 570 4GB, and an RTX 3060 12GB, with the Nvidia cards having the latest proprietary drivers at that time, and the RX 570 utilizing amdgpu. Issue has persisted from April 2023 to today (December 2nd, 2023) across Fedora Linux versions 37, 38, and 39. Worth noting that I have not tested it outside of Fedora Linux or with the regular task manager (not Icon-Only). Other details that might be worth noting:
- AMD Ryzen 5 3600 (Stock)
- 32 GB DDR4 @ 3600MHz
- Disks:
  - 1x CT2000MX500SSD1 (Mounted as /home, ext4, LUKS encrypted)
  - 1x WD Blue (Mounted at /mnt/local-backup, ext4, usually left unmounted)
  - 1x Samsung SSD 970 EVO 250GB (p1 mounted at /boot/efi as vfat, p2 mounted at /boot as ext4, p3 mounted at / as btrfs)
  - 1x Samsung SSD 980 EVO 250GB (Windows drive, left unmounted)

Additional logs, videos, and screenshots can be provided upon request
