From 5b9f5329bd922f7048084977102f23ad2845311e Mon Sep 17 00:00:00 2001 From: Olivier Fourdan Date: Fri, 3 Aug 2018 10:50:32 +0200 Subject: [PATCH] wayland: Clean up xwayland grabs even if surface is gone If the surface is gone before `meta_xwayland_keyboard_grab_end()` is called, we would bail out early leaving an empty grab, which will cause a segfault as soon as a key is pressed later on. Make sure we clean up the keyboard grab even if the surface is gone.
