From 7c2ff0449adfef596d7eea86b51f2ee40c52ad08 Mon Sep 17 00:00:00 2001 From: Andrea Azzarone Date: Wed, 18 Oct 2017 12:35:04 +0200 Subject: [PATCH] gdk: Clear GL context when window is withdrawn Some clients (e.g. gnome-online-accounts) quickly unmap and map a window. With some backends the backend surface will be replaced causing the application to crash because the GL context is still using the old surface. Clearing the GL context when a window is withdrawn fixes this. https://bugzilla.gnome.org/show_bug.cgi?id=789141 --- gdk/gdkwindow.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/gdk/gdkwindow.c b/gdk/gdkwindow.c index c0e0a7d4b2b7..79804cdacdac 100644 --- a/gdk/gdkwindow.c +++ b/gdk/gdkwindow.c @@ -5744,6 +5744,7 @@ gdk_window_withdraw (GdkWindow *window) { GdkWindowImplClass *impl_class; gboolean was_mapped; + GdkGLContext *current_context; g_return_if_fail (GDK_IS_WINDOW (window)); @@ -5768,6 +5769,10 @@ gdk_window_withdraw (GdkWindow *window) _gdk_synthesize_crossing_events_for_geometry_change (window->parent); } + current_context = gdk_gl_context_get_current (); + if (current_context != NULL && gdk_gl_context_get_window (current_context) == window) + gdk_gl_context_clear_current (); + recompute_visible_regions (window, FALSE); gdk_window_clear_old_updated_area (window); } -- 2.14.2
