Description Lucia Mrenica 2020-06-25 17:41:27 UTC

SUMMARY
Often when I start Plasma Wayland session there are few processes named xdg-desktop-portal-kde using a lot of CPU. Maybe because they fail to start properly?

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.19.2
KDE Frameworks Version: 5.71
Qt Version: 5.15.0

Is there a log I can provide next time it happens?

Comment 1 Jan Grulich 2020-06-25 18:57:59 UTC

Try to kill them all and run one with:
QT_LOGGING_RULES='xdp*.debug=true' /usr/libexec/xdg-desktop-portal-kde

or wherever your xdg-desktop-portal-kde is located.

Attach here the output please.

Same problem here.

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.19.80 (compiled with kdesrc-build)
KDE Frameworks Version: 5.72
Qt Version: 5.15.0

I killed all xdg* processes, but starting the new one succeded without a problem:
    $ QT_LOGGING_RULES='xdp*.debug=true' /usr/lib/xdg-desktop-portal-kde
    xdp-kde-wayland-integration: Egl initialization succeeded
    xdp-kde-wayland-integration: "EGL version: 1.5"
    xdp-kde: Desktop portal registered successfully
    xdp-kde-wayland-integration: Registry initialized
    xdp-kde-wayland-integration: Adding output:
    xdp-kde-wayland-integration:     manufacturer:  "CMN"
    xdp-kde-wayland-integration:     model:  "eDP-1-unknown"
    xdp-kde-wayland-integration:     resolution:  QSize(1920, 1080)

Well, I now built Plasma again, rebooted a few times and can't reproduce it with xdg processes anymore. kdeconnectd seems to sometimes still go rogue though.

Comment 4 Lucia Mrenica 2020-07-12 09:31:38 UTC

This might be caused by drkonqi getting stuck when something crashes because since I uninstalled it I don't have this issue and It (dkonqi) was always running when this problem occured. Anyway, this bug is not caused by xdg-desktop-portal-kde so this issue can be closed now, ideally if someone else can confirm.

Not OP but, after killing it and starting it, it seems the thing was resolved

Comment 7 Lucia Mrenica 2021-02-16 18:11:52 UTC

This is not an issue caused by xdg-desktop-portal-kde, but by drkonqi.
