what you can try is that you apply those two CSS properties to the card element.
transform-origin: center;
will-change: transform;
First one transform-origin: center; specifies point around which transformation is applied and second one will-change: transform; is kind of optimization for browser, that informs a browser what will change in the future.
I tested this on your website and it worked. And even before, I have 4k screen, with 125% scaling, and it was not so apparent at the beginning also.
