Description of problem: Updating from thunderbird-45.6.0-1.mga5 to thunderbird-52.1.0-1.mga5 causes the message window column headings to change format and the horisontal lines in the composition window to turn black. These messages appear on startup: (thunderbird:13379): GLib-GObject-CRITICAL **: g_object_unref: assertion 'object->ref_count > 0' failed (thunderbird:13379): GLib-GObject-CRITICAL **: g_object_unref: assertion 'object->ref_count > 0' failed (thunderbird:13379): GLib-GObject-CRITICAL **: g_object_unref: assertion 'object->ref_count > 0' failed Some screenshots showing the changes can be found here: http://www.gkc.org.uk/thunderbird.html Version-Release number of selected component (if applicable): thunderbird-52.1.0-1.mga5 How reproducible: Steps to Reproduce: 1. Update from thunderbird-45.6 to thunderbird-52.1 2. Notice the changes in the windows. The changes also appear when the .thunderbird directory is deleted: so they do not appear to be due to a local setting. The changes do not appear on the OSX or Windows versions of thunderbird 52.1 The same changes appear in thunderbird-54.0b1.tar.bz2 downloaded from the Thunderbird web site.

This is probably due to building against GTK3 instead of GTK2. You may want to check your GTK theme instead.
