From 79cf52e5566742bdbf98bce7ad7f61a5e0106448 Mon Sep 17 00:00:00 2001 From: Marius Vlad Date: Fri, 12 Nov 2021 15:15:20 +0200 Subject: [PATCH] kiosk-shell: Handle child top-level windows at destruction With the seperation of surface activation and keyboard input, a special corner case arose for child top-level windows when surfaces are being destroyed. To make sure we never pick the wrong window to activate upon destruction, we verify if the current focused surface is different than the one being destroyed.
