Martin Flöser e0f95fd913 Delay syncing internal window geometry to end of cycle ... Summary: The syncing of the window geometry to the internal geometry can unfortunately cause a freeze in very special conditions: 1. create QML component 2. a Plasma::Dialog gets created 3. It creates the DialogShadows 4. This triggers QGlobalStatic creation which locks a non-recursive mutex 5. The creation of DialogShadows creates a Registry and triggers a roundtrip on the Wayland server 6. KWin processes all Wayland events 7. This triggers the creation of a ShellClient 8. The ShellClient has a PlasmaShellSurface which requested a position 9. The new geometry does not match the geometry of the Plasma::Dialog 10. ShellClient syncs the geometry to the Plasma::Dialog 11. Plasma::Dialog updates the theme because window geometry changed 12. This accesses the DialogShadows... which is still in the non recursive mutex and we have a freeze. By delaying the sync to the end of cycle we jump out of this deadly sequence. BUG: 384441 Test Plan: The freeze doesn't hit any more. It's possible that some test cases need adjustments.
