From 9ab819684d41b5052260e11a337ce0cdee6ce3bd Mon Sep 17 00:00:00 2001 From: Mark Bolhuis Date: Sat, 13 Aug 2022 22:59:11 +0200 Subject: [PATCH] types/wlr_xdg_output_v1: Fix wl_output.done bug. If the client binds to version 3 of zxdg_output_v1 and version 1 of wl_output no wl_output.done or zxdg_output_v1.done event is emitted [1]. Also no wl_output.done event is emitted when version 2 or lower of zxdg_output_v1 is bound to. Add a version check to output_manager_handle_get_xdg_output so that no wl_output.done event is emitted when using version 1 of wl_output and version 2 or lower of zxdg_output_v1.
