From c7672699e96bacc574009015cec71e4c63efa89d Mon Sep 17 00:00:00 2001 From: Matthias Clasen Date: Mon, 16 Mar 2015 12:51:56 -0400 Subject: [PATCH] Don't pass invalid rectangles to cairo This causes pixman warnings, or worse. Clearly, something is not quite right here, if we end up redrawing tabs at a time when the allocation is set to (1, 1). For now, avoid straining the error handling in the lower layers. https://bugzilla.gnome.org/show_bug.cgi?id=746301 --- gtk/gtknotebook.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/gtk/gtknotebook.c b/gtk/gtknotebook.c index 9f6b51fd7f..65cc32e103 100644 --- a/gtk/gtknotebook.c +++ b/gtk/gtknotebook.c @@ -4832,7 +4832,7 @@ gtk_notebook_redraw_tabs (GtkNotebook *notebook) page->allocation.height - padding.bottom; /* fall through */ case GTK_POS_TOP: - redraw_rect.width = allocation.width - 2 * border; + redraw_rect.width = MAX (1, allocation.width - 2 * border); redraw_rect.height = page->allocation.height + padding.top; break; @@ -4843,7 +4843,7 @@ gtk_notebook_redraw_tabs (GtkNotebook *notebook) /* fall through */ case GTK_POS_LEFT: redraw_rect.width = page->allocation.width + padding.left; - redraw_rect.height = allocation.height - 2 * border; + redraw_rect.height = MAX (1, allocation.height - 2 * border); break; } -- 2.30.2
