Patch updated, made against v.7.4.1362. This patch contains the code which gets GtkForm to draw the background by itself.
I though the black border issue was caused by the fact that GtkForm didn't
draw the background by itself (GTK+ is supposed to do that for us, as seen
in previous patches). So I don't think, as opposed to my word in a
previous mail, this patch will fix the issue.
Instead, it could give us a clue about what happened to Mrius's gvim.
Marius, could you add the the following to the very bottom of your
$HOME/.config/gtk-3.0/gtk.css (change it in accordance with your system if
that directory is not for the one your gtk setting files reside) and then
start gtk3 vim?
```
.gtk-form {
background-color: red;
}
```
With this test, we could see which widget, GtkForm or GtkDrawingArea, is
responsible for the black border.
In addition, could you try your gvim with other colorscheme values? I
want to know where the block color comes from --- the foreground color e've
specified, the border color Vim itself doesn't specify, or the default
background color of the window when it isn't specified in client code.
Sorry about imposing on you much, but the issue is another example I cannot
reproduce. I beg your understanding.
Best regards,
Kazunobu Kuriyama
