Long delay for polymer element to display #12362

What happens when you try a non-polymer app on Ubuntu? Perhaps a Web UI app? |
|
This comment was originally written by [email protected] The sample Web UI app generated by Dart shows a delay, but it's about half as long as the polymer delay. The "connecting" message flashes but I never see the "waiting for cache" message. |

Added Area-Polymer, OpSys-Linux, Triaged labels. |

There is a 3-4 second delay between the time the content of a page displays and the time the polymer element displays.
This is an issue on ubuntu 13.04, 32bit. There is no delay running equivalent code on Win8, 64bit.
