Description Reinier 2024-02-09 18:47:05 UTC

SUMMARY
See title.

STEPS TO REPRODUCE
1. Use task manager in panel (I didn't test the icons-only version).
2. Open any window.
3. Hover the mouse over the icon in the task manager.

OBSERVED RESULT
An empty rectangle is shown and the syslog says "plasmashell[ PID ]: kpipewire_logging: Failed to query DMA-BUF formats." on every mouseover of an icon.

EXPECTED RESULT
A small preview of the window is shown.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 40 Rawhide (aka KDE 6 RC2)
KDE Plasma Version: 5.93.0
KDE Frameworks Version: 5.249.0
Qt Version: 6.6.1

Comment 1 Reinier 2024-02-09 19:03:02 UTC

There is also is line in the syslog:

pipewire[ PID ]: mod.client-node: 0x55f05ff5a780: unknown peer 0x55f05ff555b0 fd:56

This line doesn't appear on every mouseover. It seems to appear on the first mouseover of an icon after changing to another virtual desktop.

Fixed in at least version 6.0.4, probably earlier.
