Description Matej 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 Matej 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

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