[adidas VR Store] Screen Blackout Issue

Hi

adidas Korea VR_Store Link

Web èhttp://shop.adidas.co.kr/vr_store

Mobile èhttp://m.shop.adidas.co.kr/vr_store

I have a promblem like a blackout screen issue with our VR_Store developed using Krpano software.

[Description of the Issue/Error]

In the first few scenes, the movements between scenes are smooth and no problem, but the screens gradually comes to be unstable while moving and become a blackout screen finally.

This error occurred only while moving scenes including embedded video contents like the below picture but No problems while moving scenes not including video contents.

I tested on iPhone4 device with iOS: 10.3.3 and Safari 10.0, but any black-out issue was not occurred.

Additionally, website data size of adidas.co.kr was noramlly 40 Mb per VR_Store site link on iPhoneX, but the website data size was not over 1Mb on iPhone4.

(Website data size check: iPhone Settings > Safari > Advanced > Website Data)

Finally, my test result are:

1) There was black-out issue on iPhoneX with iOS: 11.4 and Safari 11.0. Additionally, website data was getting increased during access to the VR_Store and moving around. (about 40Mb each access)

2) There was NO black-out issue on iPhone4 with iOS: 10.3.3 and Safari 10.0. Additionally, website data was kept 1Mb under during access to the VR_Store.



Could you anybody look into this issue and advice me to fix this problem?

Thanks for your help in advance!

First off... Darn impressive project.

Have you tried monitoring the site using developer tools? To see why there is a 10:1 data difference between the two phones plug them into a Mac (Enable developer tools in Safari and debug in the phone settings. It has been awhile so I don't remember all the details.) At a minimum, you will see what the data differences are and what is missing during the blackouts. Same for the desktop site.

If you only work on PCs create a virtual Mac using VMWare for phone debugging. You need a small hack or two but there are plenty of guides on the net for that.

Hi,

the problem seems to a new WebGL-related bug in Safari (since Safari 11) - the same as here.

It should be fixed with the next krpano release by an internal workaround for that Safari bug.

Best regards,
Klaus
