[Sugar-devel] [Dextrose] [PATCH v5 sugar] Pulsing icon delayed by 5 seconds or so SL#2080

[Anurag Chowdhury]

Yes , I tried this solution on my end once as per Alsroot's
suggesstion of implementing alpha pulsing instead of the present
scenario  but that did not solve the problem much as you may have
noted due to the main problem lying in the rendering time of the
startup frame of the animation.
