Hi All! Some time ago, the gtk3 branch began setting long header lines so that they can be toggled between one-line-ellipsized and multi-line-wrapped. Toggling is controlled by an expander button at the end of the first line. The header is initially one-line-ellipsized if showing selected headers, and multi-line-wrapped if showing all headers.
In builds with recent Gtk libs, the rendering has been broken after toggling to multi-line-wrapped. Sometimes all lines except the first are cropped, sometimes they are overlaid on the next lines. Moving the keyboard focus to another window and back fixes the rendering, until you toggle again. Apparently, but unobviously, this was caused by the way Balsa used the GtkLabel API. An experiment has shown that a different usage fixes the rendering issue, at least in recent Gtk versions (3.20 and master), and it has been pushed to git. However, it has not been tested in older Gtk versions, where the previous code worked just fine. If the new code causes problems with older versions of Gtk, the change could be made conditional on some version number, if we can figure out where the break came. Thanks for any help in testing!
