+Subject: [spice-gtk] display: Trigger wheel scrolling after one 'click'
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The scroll wheel on the mouse will trigger a smooth scroll event with a
+delta of +/-1.0. 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.
