F40, Wayland, Plasma 6 On resuming from hibernation, several KDE apps (Konsole, qBittorrent and Dolphin) dump core. In each case, there is a slew of messages preceding the dump: May 02 09:35:00 Bree kwin_wayland[166169]: kwin_core: Could not find any suitable output for a layer surface May 02 09:35:00 Bree plasmashell[166433]: qt.qpa.wayland: Creating a fake screen in order for Qt not to crash May 02 09:35:00 Bree plasmashell[166433]: qml: The backend got an unknown wallpaper provider type. The wallpaper will now fall back to the default.

It never used to happen with F39 (using X11). I posted a less detailed report on the Fedora KDE list a few days ago, but didn't get any useful feedback. poc -- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
