YouTube Embed issues on Apple (Thin red button outline)

[qwaerstd]

Hi
I'm getting a very strange effect on YouTube embeds on Apple Macs on my site.

It's like only the outer edge of the button in the centre of the screen is showing. I've attached an image to demonstrate.

Any ideas?

Thanks

on YouTube embeds on Apple Macs on my site.

Could you be more specific? Which kind of Mac? What browser(s)? Do you have an example page? I've never seen that happen on my Mac.

It is a Macbook Pro.

The site is not launched. I could maybe pm you with a link and login?

Here is my embed code. Anything wrong here?

Removed the modest branding parameter and it seems to be fine:

Ah, glad you found a solution. Apologies ... I lost track of this thread.
