Created attachment 182025 [details] Preview SUMMARY Preview for open windows stop displayed on panel. It happens at an accidental moment in time (or I can’t find the pattern). Sometimes it happens almost immediately after the session starts, Sometimes it doesn’t happen at all. Restart session solves problem. I was able to reproduce this problem three times, on different days. If after the problem appears check system log, i see pipewire error messages (add log file) STEPS TO REPRODUCE 1. start session 2. open some app 3. work and sometimes check preview OBSERVED RESULT window preview disappears. EXPECTED RESULT window preview not disappears SOFTWARE/OS VERSIONS Linux: Manjaro 25.0 KDE Plasma Version: 6.3.91, wayland KDE Frameworks Version: 6.14 Qt Version: 6.9.1 Nvidia video driver: 575.57.08 witch close kernel module ADDITIONAL INFORMATION https://bugs.kde.org/show_bug.cgi?id=478309 I was able to find a similar old problem, maybe it will be useful too

This issue has not been repeated for the last few days. During this time, pipewire and qt package were updated several times. Probably the problem was related to any of these components and not with Plasma , sorry for the inconvenience.
