OK, I finally got it. This can be reproduced only with specific gtk-3.0
themes (including GNOME3 default), where some widget properties have
larger values than Emacs expects.
Currently Emacs expects the scrollbar width at most 16 pixels.
xfns.c:104442:
void
x_set_scroll_bar_default_width (struct frame *f)
{
int wid = FRAME_COLUMN_WIDTH (f);
#ifdef USE_TOOLKIT_SCROLL_BARS
/* A minimum width of 14 doesn't look good for toolkit scroll bars. */
int width = 16 + 2 * VERTICAL_SCROLL_BAR_WIDTH_TRIM;
However, gnome-themes-standard wants to render scrollbars in 22-pixel width.
http://git.gnome.org/browse/gnome-themes-standard/tree/themes/Adwaita/gtk-3.0/gtk-widgets.css#n511
.scrollbar {
background-image: none;
border-style: solid;
-GtkRange-trough-border: 2;
-GtkRange-arrow-scaling: 0.444;
-GtkRange-slider-width: 18;
-GtkRange-stepper-size: 18;
22 pixels = slider-width(18) + trough-border(2) * 2
I confirmed that my problem is fixed if I increase the default width to
22.
Since it happens with GNOME3 default theme, I would appreciate if it
will be fixed before the pretest, though I don't know how easy to let
Emacs to take account of GTK theme properties.
