The code added in 2212f05 triggers a scroll when the +delta is strictly greater than 1.0. This means that right after +connecting a client, we won't be triggering a scroll with the first +mouse wheel 'click'. +This commit adjusts the check so that we try to scroll when the delta is +equal or greater than 1.0. + +https://bugzilla.redhat.com/show_bug.cgi?id=1627823 + +Signed-off-by: Christophe Fergeau +Acked-by: Marc-André Lureau +--- + src/spice-widget.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/src/spice-widget.c b/src/spice-widget.c +index 853c9df6..312c640a 100644 +--- a/src/spice-widget.c ++++ b/src/spice-widget.c +@@ -1979,7 +1979,7 @@ static gboolean scroll_event(GtkWidget *widget, GdkEventScroll *scroll) + break; + case GDK_SCROLL_SMOOTH: + d->scroll_delta_y += scroll->delta_y; +- while (ABS(d->scroll_delta_y) > 1) { ++ while (ABS(d->scroll_delta_y) >= 1) { + if (d->scroll_delta_y < 0) { + press_and_release(display, SPICE_MOUSE_BUTTON_UP, button_state); + d->scroll_delta_y += 1;
