From 5ffd77c36b8f89684ae71d2ca8b0168474539677 Mon Sep 17 00:00:00 2001 From: Robert Mader Date: Fri, 6 Aug 2021 18:17:18 +0200 Subject: tests/wayland: Test reattaching subsurface after parent was destroyed and the subsurface was not previously detached from it using `wl_subsurface_destroy()`. Without 'window-actor/wayland: Remove subsurface actors on dispose' this test would fail.
