SUMMARY When applying the environment variable `QT_QUICK_CONTROLS_MOBILE=true` the application fails to launch. STEPS TO REPRODUCE 1. Install kasts via flatpak `flatpak install org.kde.kasts` 2. Run with the env variable `flatpak run --env=QT_QUICK_CONTROLS_MOBILE=true org.kde.kasts` 3. Observe that the shell returns but no application runs. OBSERVED RESULT The kasts application fails to open in mobile view. EXPECTED RESULT Kasts opens in mobile view. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: PureOS Byzantium (aarch64) and Pop!_OS 22.04 (x86_64) (available in About System) KDE Plasma Version: KDE Frameworks Version: 5.104.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION
Thanks for submitting the bug report. As mentioned in the Kasts matrix room, the crash is due to weird behaviour of the `Instantiator` inside the Kirigami `NavigationTabBar` component.

(In reply to sim6@bona.gent from comment #2) > See also: https://invent.kde.org/frameworks/kirigami/-/merge_requests/999 It took quite a while, but this has finally been merged, and today it was released as part of KF 5.109.0. It could still take a while before it hits downstream repos, though. Feel free to re-open if it turns out that the problem isn't solved by KF 5.109.0.
Last version of flathub works well in librem5 with `sudo flatpak override --env=QT_QUICK_CONTROLS_MOBILE=1 org.kde.kasts`. Thank you very much for your work.
