When I hover the mouse over a taskbar icon, the thumbnails are often empty or garbled. Wayland-session.log shows the following lines every time this happens:
"无效的参数" means "invalid argument" in Chinese.
This issue first happened when pipewire was upgraded from 0.3.33 to 0.3.39 and pipewire-media-session replaced by wireplumber. However, rolling back that upgrade does not fix the issue.
STEPS TO REPRODUCE
Identical to Bug 444107.
Empty or garbled thumbnails.
