I opened an issue on GitHub to track this. Until I can figure out the cause, I can’t suggest a workaround.

Hi Matthew.

Apologies for the delay. I have just got the information back from my client. The browser is Safari Version 11.1.1 (13605.2.8). They have confirmed that the issue does not occur on either Firefox or Chrome, only Safari has the issue. Is there a workaround I can use to trigger the event?

Many thanks in advance.

What browser / browser version?

It appears that the onFullScreenChange method isn’t being called, which means the fullscreenchange event isn’t firing. I’ll take a wild guess that this is in Safari and that Apple went and broke something, again.

Thanks again for your work on this.

I have set up a test for my client and they are observing some strange behavior on an iMac 27inch screen.

When they click on the full screen button the image is stretched slightly.

See example screen shots…

Embedded version:

(not stretched)

Full screen version:

(stretched slightly vertically)

Here is my test page so you can see html: http://www.olivierhess.com/virtual-tour-v2/example_01.php

I have been unable to replicate here on my PC.

Is there anything I can do to fix this for them?

Any help much appreciated.

Many thanks,
James.
