I think, I found the problem. Attached is a new patch (it's like the last one, but with this change). The difference between this patch and the previous is reset the phase when stop the pulsing, and use cos() instead of sin() because cos(1) = 1 Regards Gonzalo [gonzalo@aronax sugar]$ git diff diff --git a/src/jarabe/view/pulsingicon.py b/src/jarabe/view/pulsingicon.py index 2c106b0..c68a712 100644 --- a/src/jarabe/view/pulsingicon.py +++ b/src/jarabe/view/pulsingicon.py @@ -60,12 +60,13 @@ class Pulser(object): gobject.source_remove(self._pulse_hid) self._pulse_hid = None self._icon.xo_color = self._icon.get_base_color() + self._phase = 0 self._icon.alpha = 1.0 def update(self): self._icon.xo_color = self._icon.base_color self._icon.alpha = _MINIMAL_ALPHA_VALUE + \ - (1 - _MINIMAL_ALPHA_VALUE) * (math.sin(self._phase) + 1) / 2 + (1 - _MINIMAL_ALPHA_VALUE) * (math.cos(self._phase) + 1) / 2 def __pulse_cb(self): self._phase += _STEP <div class="gmail_quote">On Sat, Aug 13, 2011 at 9:40 AM, Simon Schampijer <<a href="mailto:simon@schampijer.de">simon@schampijer.de</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div class="im">On 08/12/2011 08:41 PM, <a href="mailto:godiard@sugarlabs.org" target="_blank">godiard@sugarlabs.org</a> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> From: Gonzalo Odiard<<a href="mailto:godiard@sugarlabs.org" target="_blank">godiard@sugarlabs.org</a>> This render the SVG image only one time, and then use alpha and scaling of the rendered icon and will speed up the overall activity startup.

The color seem to not be fully set for the Access Point pulsingicon in the Frame (screenshot attached). Would be great if you could have a look at that.
