Demo: Performance issue in Firefox

[kenanmasri]

Hi, I'm using Firefox Dev.

I noticed that it performs very smoothly but after a few seconds (even without interaction after page loads) The flip animation becomes slow and laggy.

I also noticed that if I only Ctrl+zoom (I mean changing the zoom level that way) the problem is solved but again happens after a few seconds.
This doesn't happen in Edge.
Not sure if it's a Firefox issue. but sounds like it's a rendering problem.

Thanks.
