Hello Rikard,
thank you!

I “fixed it” just before your test – better I found the reason and a circumvention:
I disabled Jetpacks “lazy image load” and the problem disappeared.
So is this not supported or should it be supported or do you have an idea for this?

I definitely need more performance improvement for my website – so this was one I tried to use for it.

Best regards,
Stefan

Hello Rikard,

pointed me in the right direction.

I finally used:

.woocommerce .payment_methods li img.stripe-icon {
max-width: 37px;
padding-left: 3px;
}

Thank you!
