When playing the second die by clicking on the chequer, I sometimes see the
chequer very briefly appear in the position as if the first die was moved
again, before snapping back to the correct position.
For example, 64 played 20/14 14/10 seems to be played 20/14 14/8/10. I don't
see it frequently and can't reproduce it, but it's a bit distracting when it
occurs.
Could it be something to do with the left click being to move the higher die,
then realising it should move the lower die because the higher die has already
been moved? (I have the option to display high die first enabled.) Perhaps it
happens all the time but usually too fast to see.
