Created attachment 152889 [details] The info I could get from the bug: a video, three screenshots and a TXT file SUMMARY Hi, since a week ago (more or less) there almost all the Qt apps I use in Fedora Silverblue (all of them in Flatpak format) are crashing when I use them on GNOME Wayland session. Only Krita, KGet, OBS Studio and Telegram (the latest is broken, but not by the KDE Platform) seem to keep stable. By other hand, Kdenlive, Audacious, Peazip and qBittorrent show instability issues. I can reproduce the bug opening Kdenlive first and Krita later and after, closing Krita, you can see that Kdenlive crashes. I can get the same result with Peazip and qBittorrent. Sometimes the crashes occur randomly. In apps like Kdenlive and qBittorrent, if you try to close the "About" menu, you can crash the apps. This is a message I get after closing the "About" window of Kdenlive: org.kde.kf5.kwindowsystem.kwayland: This compositor does not support the Shadow interface I think that the root of the problem are 5.15-21.08 and 5.15-22.08 version of the KDE Platform and related components like org.kde.KStyle.Adwaita, org.kde.PlatformTheme.QGnomePlatform and org.kde.WaylandDecoration.QGnomePlatform-decoration, but I'm not sure. STEPS TO REPRODUCE 1. (Example) Open Kdenlive first and after Krita on the Wayland session of GNOME 2. Close Krita OBSERVED RESULT You can see that Krita drags Kdenlive until to crash it. EXPECTED RESULT Software stability. SOFTWARE/OS VERSIONS Linux/KDE Plasma (Flatpak): KDE Platform 5.15-21.08 and 5.15-22.08 (I think) with related components like org.kde.KStyle.Adwaita, org.kde.PlatformTheme.QGnomePlatform and org.kde.WaylandDecoration.QGnomePlatform-decoration (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: 5.15 (it seems) ADDITIONAL INFORMATION
Created attachment 152938 [details] Video of the Audacious crash I can confirm this bug. Here's a video of what it looks like. I am pretty sure that crashes happen when a user points the cursor at any of the title bar buttons when a window of the application is focused. Note, though, that I didn't press any of them before the crash on the video.
Is there a chance we can get a backtrace there? It's hard to understand what's happening without.
can confirm. Fedora Silverblue 37. Faced the issue with KeepasssXC and Qbittorrent flatpak. So, I went to downgrade qbittorrent. But same issue again. But Qbittorrent Appimage on wayland doesn't have the issue. Also, switched to xorg. Flapak isn't affected in xorg.
This was a bug in QGnomePlatform that needed rebuild for ABI change in QtWayland. See https://github.com/flathub/org.kde.WaylandDecoration.QGnomePlatform-decoration/issues/5.
Seems to be addressed, thanks Jan!
