From d64bdf4755005854fc59922ed0e4cbf12ebfbdac Mon Sep 17 00:00:00 2001 From: =?utf8?q?Kristian=20H=C3=B8gsberg?= Date: Thu, 31 May 2012 10:33:43 -0400 Subject: [PATCH] xwm: Just ignore the synthetic unmap_notify As per ICCCM 4.1.4 we're supposed to withdraw the window when we see the real unmap or the synthetic unmap, whichever comes first. The synthetic unmap may come after the window has been destroyed, so let's just only handle the real unmap. --- src/xwayland/window-manager.c | 11 ++++------- 1 file changed, 4 insertions(+), 7 deletions(-) diff --git a/src/xwayland/window-manager.c b/src/xwayland/window-manager.c index 9444132..b8be54c 100644 --- a/src/xwayland/window-manager.c +++ b/src/xwayland/window-manager.c @@ -562,15 +562,12 @@ weston_wm_handle_unmap_notify(struct weston_wm *wm, xcb_generic_event_t *event) if (our_resource(wm, unmap_notify->window)) return; - window = hash_table_lookup(wm->window_hash, unmap_notify->window); - if (window->frame_id == XCB_WINDOW_NONE) { - /* We already withdrew this window on the real unmap - * notify and this is the synthetic unmap notify from - * the client, or the other way around (ICCCM 4.1.4). - * Either way, we're already done so just return. */ + if (unmap_notify->response_type & 0x80) + /* We just ignore the ICCCM 4.1.4 synthetic unmap notify + * as it may come in after we've destroyed the window. */ return; - } + window = hash_table_lookup(wm->window_hash, unmap_notify->window); if (window->repaint_source) wl_event_source_remove(window->repaint_source); if (window->cairo_surface) -- 2.7.4
