Comment 1 Vlad Zahorodnii 2023-08-24 07:56:03 UTC

Did you update wireplumber or pipewire without rebooting the computer?

Comment 2 Patrick Silva 2023-08-25 11:34:58 UTC

(In reply to Vlad Zahorodnii from comment #1)
> Did you update wireplumber or pipewire without rebooting the computer?

It's possible, i'm not sure though.

I have just updated to pipewire 1:0.3.78-1 and kwin_wayland did not crash after hte monitor leaving the power saving mode this time.

Comment 3 Vlad Zahorodnii 2023-08-30 12:19:47 UTC

It sounds like an upstream issue
