From 6a47e9a8b901b05b7a3ffb6e3929e339bbe7abc0 Mon Sep 17 00:00:00 2001 From: Benjamin Otte <otte@redhat.com> Date: Thu, 13 Dec 2018 05:22:18 +0100 Subject: [PATCH] x11: Be a lot more careful about setting ParentRelative We don't want to set ParentRelative when: - the parent window is NULL In that case we are unsure about the depth, so better err on the side of caution and avoid a BadMatch by accepting ugly output. - the cairo pattern is in an error status This should never happen - unless you start up in OOM - but better be safe than sorry. Might help with the spurious crashes in #1280. --- gdk/x11/gdkwindow-x11.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/gdk/x11/gdkwindow-x11.c b/gdk/x11/gdkwindow-x11.c index f1f2081b6b..97ada6d739 100644 --- a/gdk/x11/gdkwindow-x11.c +++ b/gdk/x11/gdkwindow-x11.c @@ -3005,7 +3005,8 @@ G_GNUC_END_IGNORE_DEPRECATIONS /* X throws BadMatch if the parent has a different depth when * using ParentRelative */ parent = gdk_window_get_parent (window); - if (parent == NULL || window->depth == parent->depth) + if (parent != NULL && window->depth == parent->depth && + cairo_pattern_status (pattern) == CAIRO_STATUS_SUCCESS) { XSetWindowBackgroundPixmap (GDK_WINDOW_XDISPLAY (window), GDK_WINDOW_XID (window), ParentRelative); -- 2.20.1
