Description oiiu19 2021-11-14 07:50:27 UTC 
SUMMARY
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:

https://pastebin.com/42VsUDin

"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.

OBSERVED RESULT
Empty or garbled thumbnails.

EXPECTED RESULT
Thumbnails correctly shown and no error logged.
