Description Harald Sitter 2014-06-20 10:58:49 UTC 
https://git.reviewboard.kde.org/r/115716/

this review introduced conditional code paths depending on
> mIsX11 = QGuiApplication::platformName() == QStringLiteral("xcb");
klauncher however is a QCoreApplication which makes platformName always return an empty string. The change effectively broke cursor startup notification (busy cursor) as now KLauncher::send_service_startup_info always returns immediately (as mIsX11 is always false) preventing the startup notification from being dispatched.

Confirmed possible fix: convert klauncher to a QGuiApplication (probably not desirable?)

Reproducible: Always
Comment 1 Martin Flöser 2014-06-20 11:50:34 UTC 
the mentioned commit is not the only reason why it would break. klauncher uses KStartupInfo which uses KXMessages which also checks the platform and would fail.

Turn KLauncher into a QGuiApplication

klauncher uses the X11 windowing system which means it should be a
QGuiApplication. This is important as otherwise all the runtime checks
for whether X11 is used will fail. This is not only inside KLauncher
itself, but also in KWindowSystem.
