Navigator goes blank after Utah upgrade

[MS12]

 As title mentions, while using the fulfiller portal the left side application navigator goes blank. If you refresh or click on any of the menu items (All, Favorites etc) it comes back. Has anyone experienced this? Cannot find any know issues or community posts regarding this.

I am also seeing the problem post Utah Patch 7. Did creating/adjusting this system property bring any relief?

We have enabled the property today as well , will keep a watch if this brings in any relief , to fullfillers they complain of slowness , servicenow suggests this was done in Utah patch 6 to expedite form loading , but this has definitely back fired as a lot of Platform users are complaining about this across multiple accounts.

We have also had reports on this.
Did the sys property help and did it affect performance on the the platform, saw some wording saying it can impact users with slower connections?

Thanks

Please can I ave an update if this resolves the issue? thanks

Observation from Day 1 - I am seeing previous behavior, the App Nav loads with the page, so the issue seems to be resolved , but the overall load time is bit slow if I look at another of my instance without the property. 
But till now its looks like it resolved the issue.

Let me know if you have any other questions..
