Invision v7 flashing between screens

Invision v7 flashing between screens. After I google the issue, it seems like people report this when 2018.

Issue:

1. v6 no flashing issue between screens
2. v7, flashing issue between screens

Tested Platform
1. Windows Chrome, Firefox, Edge (OS and browsers all updated)

2. Also iOS Safari, Chrome, Firefox (OS and browsers all updated)

It is really annoying, any solution for that?
