From 9de3a86d736f70c4d45550649ba62a935369b146 Mon Sep 17 00:00:00 2001 From: lukefromdc Date: Tue, 3 Jul 2018 15:59:56 -0400 Subject: Tray: simplify force-redraw, use code that actually works Prevent most corruption of tray icons and reduce by half incomplete rendering of them, replace a never-built code block that could not be built, and replace (deprecated) direct expose handling with gtk_widget_hide/gtk_widget_show_all *Note that this is needed for GTK 3.23 but may help remaining icon issues with GTK 3.22 as well and is simpler code in any case --- .../notification_area/system-tray/na-tray-child.c | 47 +++------------------- 1 file changed, 5 insertions(+), 42 deletions(-) diff --git a/applets/notification_area/system-tray/na-tray-child.c b/applets/notification_area/system-tray/na-tray-child.c index 6efae8f8..d29da781 100644 --- a/applets/notification_area/system-tray/na-tray-child.c +++ b/applets/notification_area/system-tray/na-tray-child.c @@ -561,48 +561,11 @@ na_tray_child_force_redraw (NaTrayChild *child) if (gtk_widget_get_mapped (widget)) { -#if 1 - /* Sending an ExposeEvent might cause redraw problems if the - * icon is expecting the server to clear-to-background before - * the redraw.
