Stripe Payments and OneStepCheckout
If you are using the official Stripe Payments extension from Stripe, you can experience some rendering and layout issues depending on your Magento configuration.
Symptoms: When Stripe Payments is enabled, the form for "I have a different billing address" does not render, and the Payment Methods is rendered in the wrong position.
Solution: Configure Magento to Display Billing Address On on Payment Page. See here for more details.
(Tested and verified with Magento 2.4.2, stripe/stripe-payments 2.5.7 and OneStepCheckout 1.2.046.)
