GrabHelpers use a 'captured-event' to steal events and emulate modality or grab-like semantics. There can be issues when you try to use multiple GrabHelpers stacked on each other. As Clutter follows the DOM-like semantics of "first come, first serve", when a second GrabHelper connects to 'captured-event', its callback will only be processed *after* the first GrabHelper's callback is called. This breaks the expectation of narrowing modality where new modals take priority over the old ones. Solving this globally in a cleaner manner would require a rewrite of pushModal/GrabHelper. As a stopgap fix for now, use one shared 'captured-event' handler between all GrabHelper instances, and delegate to the individual GrabHelpers. https://bugzilla.gnome.org/show_bug.cgi?id=699272 |
