iframe does not work correctly in firefox, what is the reason?

Question

Mozilla Firefox

there is an iframe



It has an image and a button, by clicking on the button the image changes to another, larger one.

In all browsers everything works fine, but in firefox, when changing the image or even when scrolling, it looks like this at first and only then is it completely loaded.

Answer 1

Perhaps hardware acceleration is not enabled in the browser settings, there were no such problems on normal machines.
