Iphone 6/JQT issue

[vbcodep]

I have an application that works fine on Iphone 4/5 but seeing problems on Iphone 6 in both safari and chrome. 

The flow.

1. Use picks a field to update 

2. List is retrieved using ajax (function locationPicker) which returns list via <DIV>...</DIV> (perl code below)

3. Item is selected and href is fired to transition back to main page. (function setLocation) 

4. On transition back to the original anchor there is a flash that doesn't occur on other platforms except iphone 6. 

I've highlighted where I believe the flash it occurring (while the original anchor is being loaded).

Any ideas on what might be causing this problem?   Has anyone else experienced similar issues?  

TIA

John
