LayerShell windows with non-spanning anchors (AnchorTop|AnchorRight)
crash the compositor when made invisible because Qt briefly resizes
the surface to 0 before unmapping it. Wrap GamingHUD in a Loader so
the window is destroyed rather than hidden.
Replace the generic 'Yes / Cancel' exit dialog with 'Keep Playing /
Leave' in both the Game Center header and the QS tile, matching the
mental model of a couch user.
The 'Launch Hint' QS tile is now hidden (available: false) when
gaming mode is off so it does not clutter the regular action drawer.
Add a gamingModeEnabled bool and a gamingDismissHintEnabled bool to
the shell settings plugin, persisted in plasmamobilerc [General],
following the same pattern as convergenceModeEnabled.
Two new quick settings tiles:
- org.kde.plasma.quicksetting.gaming: toggles gaming mode on/off,
shows explicit on/off label matching the convergence tile style.
- org.kde.plasma.quicksetting.gaminghint: shown while gaming mode
is active; dismisses the Game Center hint.
Both tiles are added to the default group in quicksettings config.
