Committed on 24/07/2023 at 16:52. Pushed by davidedmundson into branch 'master'. delete platform cursor before Application We want the platform cursor to have roughly the same lifespan as the application. By using QObject parent mechanism, this gets deleted after the Application destructor in the QObject destructor. This causes an issue that removing an event filter (used by the X11 cursor) calls into the application singleton which is no longer valid.
