http://bugzilla.opensuse.org/show_bug.cgi?id=1176626 Bug ID: 1176626 Summary: problem with flatpak and QT_QPA_PLATFORM on Wayland Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem Assignee: screening-team-bugs@suse.de Reporter: dfaggioli@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- the Telegram flatpak does not start, if within a GNOME Wayland session. Trying to start it manually, this is the output: flatpak run org.telegram.desktop (process:2): Telegram-WARNING **: 16:39:07.608: Unfortunately, GTK integration conflicts with qgtk2 platformtheme and style. Therefore, QT_QPA_PLATFORMTHEME and QT_STYLE_OVERRIDE will be unset. Telegram-Message: 16:39:07.609: This can be ignored by setting TDESKTOP_I_KNOW_ABOUT_GTK_INCOMPATIBILITY environment variable to any value, however, if qgtk2 theme or style is used, this will lead to a crash. Telegram-Message: 16:39:07.609: GTK integration can be disabled by setting TDESKTOP_DISABLE_GTK_INTEGRATION to any value. Keep in mind that this will lead to clipboard issues and tdesktop will be unable to get settings from GTK (such as decoration layout, dark mode & more). qt.qpa.xcb: could not connect to display qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb. Trying to run it like this: QT_QPA_PLATFORM=wayland-egl flatpak run org.telegram.desktop it does start. On an Xorg session, it starts without issues. I'm reporting this here instead than to Telegram or flathub directly, is that installing exactly the same flatpak on, e.g., Fedora or Ubuntu works flawlessly while inside a Wayland session. So it feels like it's something specific to openSUSE. -- You are receiving this mail because: You are on the CC list for the bug.
