+Subject: [PATCH] vulkan/wsi/x11: fix use of uninitialised xfixes region.
+
+If you are in the sw + no mit-shm support, we don't create the xfixes region,
+so don't try and use it in the same scenario.
+
+We are seeing some gtk4 apps crash with BadRegion reports due to this.
+
+Fixes: bbdf7e45b15f ("wsi/x11: Hook up KHR_incremental_present")
