Created attachment 476788 [details] Reduction of the bug in a single html file I have attached a reduction. The problem only seems to show when using a 'complex' background (a pattern in this instance but filters can also be problematic). 1. Click 'Deal!' button 2. The top card will move into position with a view-transition 3. Notice that the numbers seem to count up in the stack of cards at the bottom 4. Set the background of .card to a static color and notice the problem does not persist
